First of all you need to make use you use CSRF only on URLs which need it (have CSRF vulnerability e.g. transactions) and these URLs to the Protected URLs list in ASM CSRF screen.

 

Secondly:

 

Version 11.5.4 has a known CSRF bug (ID474256) causing False Positive, more information here

So if you are affected (CSRF protection is needed in frames) then you need to upgrade to v12.x
