I’m glad that worked for you
Don’t know why the Gear wasn’t showing the Presentation Editor though
To re-save your morph it’s the same as when you first saved it… Go to File ->Save As… ->Support Asset -> Morph , navigate down to your morph and only check it, it will back check up the tree for you. Then just enter your info as before if it isn’t already filled in and click ok.
note: make sure you use the same names like product, item and so on, otherwise it will create a new morph slider.
hope this helps
