Modify LineStyle Scale

I am using the command 'SelectBy Attributes' to select all my Lines and Line Strings.  I'm then using the 'Modify LineStyle Scale' command as shown below to change all of them to 50 scale.  This works great and changes most of my LineStyles.  But several get changed to 600 scale or don't get scaled at  all.  If I run the command several times all the LineStyles eventually get scaled correctly.  Any help on getting this to work one time would be greatly appreciated. I'm using ORD but having the same problem with SS2.  I can post this to those communities if preferred but seemed like a MicroStation issue so I posted here first.  Oh, I uploaded my file also in case anyone wants to reproduce the issue. Thanks again for any help.
