Gallery Bug

I am unable to remove builds/households that were uploaded to my public gallery. I uploaded them from my XBOX to transfer creations to my PC's library with the intention to immediately remove them from my catalog page. It took about three tries to even upload them without a timed out/connection error. I am also unable to edit the descriptions, bathroom/bedroom counts, etc. Some builds/households I downloaded off the gallery were from other creators that I renovated for my personal saves, and I don't want to take credit for any builds/households I did not make originally and share them on my gallery (personal preference). It has been an issue for about two weeks.
