Can't Delete Uploaded Maps in the VTT?

Has anyone else been unable to delete uploaded maps in the VTT? I was able to delete them before, but when I went in to clean it up a bit and remove some duplicate maps I had managed to put in there (the general maps management, not in a specific campaign) the three dots don't do anything when I click on them anymore, and I have no way to manage or delete an individual map. It's not a massive deal since I'm nowhere near storage capacity, I was just trying to make it a little easier to navigate for myself.

Same here, can´t delete some of my uploaded maps

Yeah, I've tried it on 3 different devices and 2 browsers, and just nothing happens when I click or touch the three dots to bring up the context menu for any uploaded maps. Not sure what's going on! 

Update: I've been playing around, and I at least found the reliable trigger. If I upload a map and just have it in my account, I can edit and delete it at will. But once it's been added to a campaign, the ability to edit or delete becomes locked. And it stays locked even after removing it from every campaign (I only currently have 2, so it's easy to double check). So something in the system doesn't appear to be releasing the map from active campaigns as far as the browser is concerned, despite being deleted from the individual campaigns. Hopefully this helps someone track down the issue! I have a few duplicate maps and stuff with mistakes from when I first was getting to know the system that I would really like to be able to remove if I can!
