After closing the designer I looked into the console and I see that is it flooded with messages like the one below.  
Should I be worried?

I don’t think you need to worry about this - it should be getting fixed soon, if it’s not already, but basically what’s happening is that in a certain case the subscription model is tricking the UA client code into deleting items it already deleted. Looks scary-ish, but it’s a bookkeeping error that doesn’t negatively effect you overall.
