The unit is a Roku Express and if I cover up the sencer in the front of it it stops a scrolling until I uncover it and resetting all the devices in the house did not help
That confirms the scrolling is caused by IR input to the Roku.
Now let's see if that signal is coming from the Roku remote. Does the scrolling continue when you remove the remote's batteries or cover over the top of the remote where the IR sender is located?

Yes even after removing the batteries from the remote the screen still continues to scroll on its own it does not stop unless I cover up the front of the device and once uncovered its starts again.... I have reset all the phones tablets modems and routers anything electrical in my house has been reset and there is no other Roku remote in the house that could be affecting it
