Swift Sprite Roof Decals

We have a 2023 Swift Sprite dealership special. Over the last few weeks we have been washing the caravan ready for the new season and have noticed some large air bubbles appearing in the black decals above the front windows. We have tried to smooth these out but they just reappear. Has anybody else experience this problem? Can you recommend an easy fix, or is it a trip back to dealers to be fixed under warranty.

Cheers
