Adding new tasks - risk of accidentally pulling in an existing one

This is mostly operator error, but a few times now we have accidentally accepted one of the (rather random and spurious) suggestions that Wrike comes up with that then pulls in an existing task rather than creating a new one. 

This would not be too bad, if you could then just delete it from your project and start again - but deleting also removes it from the project it was originally in - and it is quite difficult to find out whose plan you have messed up. I am also not sure if pulling it in duplicates it, or removes it from its original location anyway? 

Can anything be done to make it more difficult to make the mistake in the first place? (other than me being more careful!)
