Why NLA animations are limited to 6 when exporting to FBX? I'm getting this problem when trying to export from blender to any other program in Fbx format using NLA stacks for animation, when exported it only seems to save 6 out of 12 animations 


Don't know if it helps to find the problem, but 4 out of 6 of those unexportable animations were clones at first and later modified.

FBX export settings used.
I found out what was wrong if anyone else got the same problems, all exporting NLA strips are controlled in Nonlinear animation tab:



Found it in the documentation:
