The height of the strip and the Anchor going crazy without touching it. No one using my PC and this account except me. I just log in to upload some new photos and I see them not in their place anymore, each times I have to move the in the previous position.

This happens many time recently! I wonder if anyone has the same problem?
I have had this problem within the past month as well — though I cannot keep checking back to see if it is persistent or not, since I have larger bugs with the Wix Forums app itself to have my attention on right now.
I only upload new photos to the album. Then I saved it and closed the browser.
Next day, or next few hours, I log on again and go to the editor page to add some more photos, and I see they're changed!
Now I HAVE TO REDO it every time they're changed.
This is like the after you clean your house and go out for a dinner, after 2 hours you come home and see a mess!
This happens a lot recently, I submit a ticket to the CS team, but they're not helping at all.
Very annoying!
