Bubble marks on smooth PEI sheet after removing print

After removing my most recent print i noticed some small bubble marks on the printbed sheet along the outline of the object, most pronounced at the corners. The sheet is also visibly warped in those spots. They never appeared on a previous print.  What are those? Could they be related to the higher first layer temperatures, that input shaper needs? (230 vs 215 for PLA, which is what im using). This was my first "longer" (6-7 hours) print with the new input shaper profile.

And do i need a new sheet now?

RE: Bubble marks on smooth PEI sheet after removing print

Bubbles like these often appear when a print has been firmly adhered to the build plate. 
If you clean the other side of the build plate and use that, next time, the bubbles formed on this print will probably disappear

I try to make safe suggestions,You should understand the context and ensure you are happy that they are safe before attempting to apply my suggestions, what you do, is YOUR responsibility. Location Halifax UK

The bubbles should disappear by themselves over time. If they spread to the entire printing plate, moisture could be a problem.

Carefully remove the print object only after the printing plate has cooled down completely.
