" Save Level as " Breaks all my bindings

Hi. I’m having some issues with the " Save Level As " option. It works only it then flips to the newly saved level when the save action is complete, I open the level sequencer only to find out that all my bindings are broken, my character and camera are all lit up red. I have no idea how to fix this can someone please advise me on how to fix these bindings. Iv tried a few things but nothings working.
Just out of curiosity, maybe I’m approaching this all wrong, How do i duplicate a level??
Thanks
