Create Region FX grayed out

[Lombardi]

I am looking to use the Drum Replacer on a kick drum track, which I have done before on other songs.  After selecting the clip, (entire track) when I select Region FX from the menu above, or right clicking on the track itself, the option to "Create Region FX " is grayed out (as is all other choices).  This is true when selecting other tracks as well, but not all tracks in the same file.  What am I missing?

Select the clip by shift clicking on the lower half or selecting it in the inspector on the left.

Then look again.

There are restrictions on Region FX. Maybe regions that have audiosnap or groove clip looping are denied region FX. The reverse is true, namely that looping and audiosnap are disabled within a region FX.

This may have been the case, and I had forgotten that audiosnap had been used, but when I bounce each track to clip, I was then able to create a Region FX.  So for whatever reason, it is now functioning correctly.  Thanks for your help.
