Cannot edit achievement icons on a game

Hello, about 1-2 weeks ago I made achievements for my games so I can tested them in codes. But since the icons for those achievements are not complete yet at that time, I used a placeholder icons. But now when everything is ready and I want to replace the icons, it seems that I cannot replace the current placeholder icon with the updated icon. Can you guys please tell me what should I do in this case? Or should I just delete and re-populate the achievement list?

Hi, What’s the app id? I can try to reset the timer so you can edit the achievements again.

Thank you for the fast responses. I have 3 games with the same problem. The app id:
5666752bd55930a56e000f93
5666778abbddbd0a15000f4a
56667928e694aa7c03001057

It looks like the games may have been approved early which causes a 14 day timer to start for editing achievements. I reset the timer, so you should have another 14 days to do the achievements. We will increase the achievements edit time if it continues to be a problem. Thanks
