Why is Pro Tools 11 deleting my files?!

Last night I had all my tom fills I did a cleaning of files out at end of session. Today all my tom fills are gone! I had to get these files off another hard drive save.

I put them all back and all is good.

Then I made a duplicate track of one of the tom fills track next thing pro tools grays this track out! Ive never seen this before.

Then pro tools keeps telling me I need more memory?!

More memory?!

I have a new computer with DDR 4 32 gb of memory and my processor is an i7 9530k what is going on here?
