OpenRoads Designer - Cross sections in uneven stations

Hello there.

I am using OpenRoads Designer 2021 R1.

I would like to create cross sections per 20 m in St. 2+005, 2+025, 2+045, 2+065 etc. so I set my Named Boundary dialog like this:

But even though the first cross section is cut at St. 2+005, the rest are cut at even stations 2+020, 2+040, 2+060 etc.

In the old software I would toggle off a station lock, but I cannot find that in ORD.

Where do I tell the software to cut at 20 m intervals counting from the first station?
