If it is a lot of corners, you might have a vapor emission problem.
It could be a peel & stick problem too.
First, try a heat gun, (not a blow dryer) Heat the tile and the glue beneath. Careful not to scorch the tile. Being plastic, it will melt! When both the tile and the glue are good and HOT. push down and stand on the tile for 5 minutes.
If that doesn't work, VCT clear spread if you can get it under there uniformly, without making a mess! It can't have globs. Let the adhesive sit open under the tile. Wedge the tile up with some thing so the glue can air out and get tacky.(about an hour) Don't set tile into the wet VCT clear spread adhesive!! Clean any topical glue mess up after the repair, with mineral spirts.
Removing the entire tile is the next fix. Anything else is going to be temporary.
