Static clean plate in remove module

Mocha Pro V5.6.0
Fusion 16


Having a few problems in Fusion if you could help please.

Is the input for the remove module ‘input3’? When I connect to it, I can’t get the Mocha GUI to see it. If I render a frame with the clean plate set to ‘none’, ‘Remove_input’ appears in the list of clips, however when I try to view it, nothing happens.

When I try to use ‘Insert_Layer’ as an input, the clean plate is visible but doesn’t follow the tracking and stays static through the moving mask.

Clean plates created from within Mocha seems to track properly.
