Hi this is not a bug.
There is a short limit ( I think its 10m) for suggesting an in-app location edit.
If you go beyond that it snaps back.
You need to log in to the wayfarer site select help and then the help bubble.
The good thing is that you can provide photos as evidence that the pin is in the wrong place.
But for reference, staff have his/her own judgement about placement depending on evidence provided
Example
So its in your best interest to provide as much evidence as possible
Thanks! Now it’s clear!
So, I would need to go make some photos then. I think it’s quite clear with updated Google maps, but to make sure that it will end up in correct location I will try to support it with photos.
Would be nice to have some info in the game app as I was fighting this for some time already 
Good luck
