Unselected object in edit mode

Question: When I go to edit object “M” , object “TT” is also visible. and when I return to object mode object “TT” completely disappears. It’s like Edit mode and object mode are mixed up. I know I probably inadvertently hit some key combo but I cant figure it out. Ughh.

It is not a hide issue beause all the other hidden objects appear with “alt h”

Thanks for you time even if you do not know this off the top of your head. -Nick


You didn’t post the .blend file.

I’m gonna go on a hunch and say it’s probably one of the modifiers doing it.
