[ORD 2021 R2] Vertical Point Control not working on Linear Template

Question

I have a corridor that models a shoulder and ditch around the outside of a cul-de-sac. The corridor is made up of a linear template attached to an EOP linear feature with an active profile. I have a couple of Parametric Constrains that work as they should. I also designed two special ditch profiles (stored in the geometry file, but designed on the Bulb_EOP alignment, not on the ditch element itself.) I believe I added the point controls correctly to modify the ditch elevation in the corridor, but the dynamic XS viewer doesn't reflect the modified ditch profile. It looks like the point control is not being used. What am I missing? I have successfully used this template with other corridors. (The pavement surface is modeled in a different corridor.) 
 DitProN is for a ditch segment at the north side of the bulb, and DitProS is for a ditch segment at the south side of the bulb. These can be seen as the two heavy red profiles in View 5 (the profile view). View 7 shows that the special ditch profile point control is not being applied. 
 I'm not getting any follow-up help from Support so I thought I would post here.

If I can add to what eddiegiese has already suggested with a few random thoughts. Have you attempted the following debugging items? Without seeing the ITL and corridor files, I can only provide these general corridor debugging steps that may or may not be useful. 
 my initial thought is that you need to add that Ditch Geometry as a corridor Reference depending on how you&rsquo;re ITL is built. 
 other more general debugging steps below. Good luck with you&rsquo;re issue. 
 
 Wiping out you&rsquo;re Point Controls and rebuilding them, for the Linear Template? This is something I seen to have to do pretty frequently when my reference geometry changes. 
 have you tried changing you&rsquo;re point control type from Linear Element to Corridor Element? 
 Does you&rsquo;re Stationing have prefixes and if so, are you using them in you&rsquo;re point control layout? 
 Have you tried to set any ground seeking points in your ITL from using &ldquo;active&rdquo; to assigning them to a actual terrain file? 
 Have you checked general housekeeping items like you&rsquo;re Terrain being Active as well as ensure you are using the correct Vertical Profile for the ditch? 
 Lastly, and as a last resort, take a brand new seed file and start over? I&rsquo;ve had to go to this extreme a few times in ORD 10.10. You can export you&rsquo;re point controls and parametric constraints as a CSV from you&rsquo;re old corridor to make rebuilding a bit simpler.

Thanks for all of the suggestions. I had tried most of Matt's suggestions prior to posting, including rebuilding the corridor, but thanks anyway. It may help someone else. 
 What finally worked was splitting the corridor and geometry at the middle of loop into a north-side one and a south side one. This has been a limitation that in a loop situation you can't tell the point control to tell which station to pick. The workaround is to split it at the middle of the loop. Support said not to expect any change soon but there is a defect filed for this issue.
