Hi Jimmy,
Thanks so much for your report!
The slide width issue has already been reported here: WIP: Nestable slider: selecting a slide changes slide width on canvas - #3 by timmse
As for the background image editing capability: we can’t replicate the issue (tested by two of us). Please send temporary login credentials and a link to this thread to help@bricksbuilder.io using the email address you used during the purchase.
Best regards,
timmse
