Images disappearing every time I move image block.

Site URL: https://cheetah-raspberry-84by.squarespace.com/

Hello, 

I am actively working on two different Squarespace websites using two different themes.  Both are in development and plans have not been purchased for them.  The URL I provided is for my own personal site I am building for my business, and this problem is also happening on a client's website I am actively working on. 

Every time I click and drag an image block, the image disappears and I have to re-upload it, which is very frustrating.  These are two different themes and it doesn't seem to matter what style of image block it is, whether it is a card, inline, etc. 

The problem seems to be very consistent.  Even after I save my edits and try to open the URL for the site in a separate incognito browser, I can confirm that the images are gone after moving the image blocks. 

This problem is a major roadblock and is severely inhibiting my ability to deliver sites to my clients.  Has anyone else run into this?

I am building the sites on Windows 10 using the latest Chrome web browser.
