Help! Possible rubber damage

Ok so I recently replaced my rubber. 

Joola Rhyzm P and Donic Acuda Blue P3

Not more than 2 weeks of usage..

I stored my racket for a few days...and POSSIBLY due to the heat, the rubbers suddenly formed some very small bumps. 

I will vouch that the one who replaced my rubber was a professional, so we can rule lousy rubber replacement etc.

Question:

1 What is the cause? Like i said, i lt could have been the heat of the summer...but id like to hear other on these.

2 what can i do to rectify this?possibly reglue my sheets again?

3 how will this affect the rubber on a game?

THANKS IN ADVANCE...
