Can't save any changes in snap store

Every time I edit my Snap’s (private) store listing by added a logo or description, the save button is greyed out and my changes aren’t saving (i.e I reload the page and they are gone).

Here is a screenshot: https://drive.google.com/file/d/1Ah_0puRh3zAMvaNuSRnDxMVe7cDJtWVf/view?usp=sharing

What do I need to do to be able to save my changes?
