Prime tower spreads from back to front of build plate about halfway through the build

So I sliced my model, and the prime tower looks odd. Not sure how to fix it.

I am having the same problem.

So I changed the prime tower type, I guess it defaults to the new one that was added in the last firmware, I do not think it works right. but after changing the type back to square I think, I have no issues.

How do I do that?

edit: figured it out.

Thanks a lot
