The two big ones are rise late very slow , I can watch them during get the meal from the bottom of the U boot.
An indication that I do not totally glue air proof the two halves together.
All the other bubbles I don`t know. I choose an other maker of resin.
This time the bubble do not disappeared.
Side note:
I do the resin in three layers. After the first was dry I place the U boot as I like.
Fill careful the next level of resin in.
