Overwriting PA's?

[ironman24682]

After doing a bunch of missions I realized I had a ton of money so I figured I might as well learn all the PA's that you can buy in the shop, after buying about 3/4 of them I started learning them and halfway down the list it appears you can only learn so many before you have to overwrite an old PA to learn a new one. Do you think its because this is the demo version? I never ran across this problem in the full PSU game...

Every version of PSU has a PA cap of 36.
