Remote only works when I hold the ‘del’ button in

Hey guys I have tried looking up this problem with no success so here I am.

So I pressed the ‘del’ button on my remote while using Kodi (I was trying to remove a source) and it took me back a page and now the remote will only work while I hold the ‘del’ button in. It is so frustrating and I have no idea how to change it back to normal.

Any help would be greatly appreciated.
