My iPad Mini seems to be ghosting

I recently got my iPad Mini lcd replaced last December 2017. It was working fine after that but I recently noticed that the bottom right of the screen (right side from the home button) seems to be popping out. When I push it back, the screen would start opening apps or typing by itself. Then I found out that it was ghosting, then I also found out that the right side part from the home button is where the digitizer cable could be found connecting to the logic board. The good thing is that the ghosting would stop when the lower right part of the screen would pop out again and all would be normal. Now my question is, could this just be a loose cable? Does it really require another repair. I dont think in my own side that the digitizer on my ipad is faulty since it works fine when the lower right side would pop out a little bit.

I really am worried on my iPad. A reply would be very grateful for me.

Thanks in advance.
