Hello and welcome, @Claude
I’m afraid the images are quite a bit blurred when I zoom in to see what’s happening. However, what I can see is that they’re both .vit files, which is an individual measurement file and a multi-size measurement file is .vst.
Here is an image of my f(x) - formula option - menu where the measurement names are listed and I can assure you that each one has its own measurements:

I suspect that the problem may be in your measurement file (SeamlyME), but I can’t be sure.
You can only load one measurement file at a time, in Seamly2D and the pattern should adjust itself to that measurement file. So if you use the same measurement areas in all of your measurement files, you shouldn’t have a problem.
If you can send me the pattern & measurement files, I can have a look for you - you may send them by personal message, if you wish.
