Silicone bubbles

I just noticed these bubbles in the silicone sealant after doing some cleaning. They might have been there before but I am not sure. It is a 40 gallon breeder. Should I worry?

No need to worry, aslong as the actual corner is full of silicone you are safe.

Thanks. I checked some pics of the tank when I got it and the bubbles were already there. It has been 7 months and the condition of the sealant has not gotten worse. Knocking on wood! thanks.
