Folder bug

[6meterkuk]

Hello, I have an Android 6 phone (marshmallow) and I experienced a weird bug. I created a folder with 2 apps inside, pretty normal stuff. But some time ago I removed one of them because I didn't use it. It was then that I realised that the folder was broken because the other app inside didn't 'pop out' like it should. It stayed in the folder (which I couldn't open) so I had to go in google play, write the name and then open the app.
I tried deleting the app and then this happened:

(Yes, other folders work normally. Only this one is affected)
(Yes, I tried rebooting multiple times)

Have you tried a long press on the folder to see whether you get the option of removing it?

If that doesn't work, well folders are a feature of the launcher you are using. So can you tell us what launcher that is, or if it's the default one can you tell us what phone you have (because default means "I'm using whatever launcher the manufacturer included")?

It is the default launcher

I dont know what the problem is, its probably not fixable
