cant sub anyone, need help bugs forum no good

Ok, well i cant sub anyone anymore. When i try to drag a sub across it comes up with a dropbox to sub the player i have enver seen before, its a long title box with red writing sometimes with the postion of the player but it wont let me make any subs at all. Below is an image of what i am talking about, however the red text i stated that comes up is not showing in this case.

Does it have something to do with custom views in the tactics screen? It was showing all players at one point and wouldnt let me click on PKD for picked so i had to change it on the custom view screen. I see no way of stopping this though

You probably cannot see how large the box is there as its transparent but it is 4x the size it should be normally when dragging and dropping.

ok, i found out its something to do with weird custome views and i have found out how to delete them. Case closed i guess but beware lol.
