Should be fixed with http://commits.kde.org/plasma-desktop/5c966a42554fc0db374326b5fcdeb03e30d6cd6e Feel free to reopen if not.
In Plasma 5.8 still not fixed. Empty buttons are only for settings actions in dashboard!
Can confirm, still not working in 5.8.1. Also these empty shortcuts can not be removed individually. Right-clicking them does not provide context menu. The only way to get rid of them is to remove all recent applications.
It was fixed, but I forgot to merge it in 5.8. It will be in Plasma 5.8.2. Sorry for the delay :(
