Text jumping to the bottom of the box instead of staying at the top

Hi there, having a bit of trouble with my InDesign at the moment and was wondering if anyone can help. I have reached out to adobe support and all they say my text is too big for the box and I have no issue. 

I have had all my templates set up for over a year now and never had an issue until my text started moving to the bottom of the box this week. I used to be able to just go in to the template and add the information I need over top of whats there and there is no issue with movement. 

My adobe account is the only one having an issue as other team members are able to open the templates and make changes in their accounts without this happening (both on windows and macs). This issue is happening on both my mac and my macbook pro so I am confident its my account. 

Adobe also suggested I create all my templates from scratch but I don't see how this will help my issue when its only my account thats doing it, all other users of these templates are fine. Its also not a feasable option as I have hundreds of templates.

I have attached a video to show whats happening. All the text should be able to stay the same as what is originally shown, but every time I go to backspace, enter or change the text (virtually do anything) it drops to the bottom of the box and oversets the text. 

Even if I create a new document and copy and paste the contents of the templates into another document it still does the same thing. Can anyone shed any light on how to fix this?
