RW Banner Image Error

There is an issue with using the built in banner image. After having one of my themes give me grief, figured out the issue. Using Kiki theme as example, after you fiddle with the banner image settings, even if it is changing it to another option and back, after a few times the image path is …/…/…/…/…/…/…/…/…/…/…/…/…/…/…/…/image.jpg. I have a video showing what happens, should be able to duplicate it. Using latest beta 18121. FYI while trying to do this, crashed several times on export, randomly. Had publish set to local folder, and using the export option in the menu. Both were a bit crash prone.

Seems to be trying to embed the video. bit.ly/2b5VIng
