It's hard to tell what's going on just by looking at your screenshots. You need to describe:
- Your intent (what it is you want to accomplish)
- What orders you gave to which units in order to obtain the desired result
- The actual result (what is happening that is unexpected)
And show that with an example in a screenshot, demonstrating the problem.
Looking at the screenshots you posted, it seems that the units are all deploying to fallback lines. Nothing wrong with that at first glance. Although it's a bit strange that you have drawn all these small fallback lines in addition to the frontlines, but again, not knowing your intent, it's hard to tell.
In each case however you have a warning telling you have orders assigned to no divisions at all (see the red arrow I added below pointing up to the warning):
which may indicate that you are not issuing orders correctly, and so the units are not behaving as you expect. In other words, bad input produces bad output.
Lastly, you mentioned you recently bought DLCs. Are you saying you didn't experience these issues before?
