Microsoft SwiftKey app

I have this as my keyboard on my Samsung & for the most part it's been fine. 

Recently though it's not been carrying out the shortcuts I'd put in (which had been working fine for years until recent). 

I go to open the app & noticed its not even there in my library.if I access apps via settings then it's listed but as an enable/disable app not an 'open' app. It appears I can't access the apps own settings. 

The annoying thing with the shortcuts is that they don't work or not work, they some times work & some times don't work (when they always used to work every time until recently).
