Void behind dot and dabbed backer boards?

Void behind dot and dabbed backer boards?

Void behind dot and dabbed backer boards?

Will the voids behind dot and dabbed backer boards cause any problems or cosmetic issues once tiled and used in a bathroom?

Will the dabs be cold bridges to the masonary wall for example?

Is there any solution, or is this not an issue?
