Castle Invasion 3 (Birthright) - why is my number of player units restricted to 6?

According to the below I should get 10 and I looked at Youtube to confirm that but see my pictures below - can only choose 6

And before that it was limited to 7 units (which I thought was normal and I think I had the same number for Invasion 1 & 2) - I lost the battle the first time with a random & haphazard layout and after spending 90 minutes figuring out a hopefully better layout I noticed the number dropped to 6 which clued me in that something was definitely wrong. So I tried demolishing 1/3 to 1/2 of the buildings and got rid of the 3 puppets to see what would happen and actually that drops the available units down to only 4 (I didn't take pictures of that). So what's going on here?

I think it's the way your buildings are positioned. They're squeezed together and not rotated so the other deployment spots don''t have anywhere to be.

The place where player units can start is based on the buildings (ususally it is their entrance...), I am guessing you have accidentally blocked too many of the places where your units could start. I suspect simply rotating some of those buildings would end up solving your problem (or rearranging them to have more space around them).

The comments are right. If you want to keep this same layout, rotate the buildings so their entrances are on open tiles. Otherwise the units will not spawn.

Thanks - I didn't know unit placement was determined by buildings (I just went back and checked #33 and #34 of the in-game tutorial - it is mentioned in there but easy to miss. Really the building placement should be merged with the battle prep screen for invasions. And I had no idea buildings are rotatable and didn't see that mentioned in the tutorial)
