Thanks for comments and ideas for getting rid of them,

If you hover your mouse over the warning chevron, it will give you the reason.

Thanks a lot, I’m kind of familiar with the “mouse-over information box”, but unfortunately it doesn’t give in this special case the extra info.

So what does it give?

Unfortunately nothing. Just the Arrow over and then no further information.

Go to Menu > Operations and look for any errors in the Log tab.
