Quantus terminated normally yet produced errors. [resolved]

I'm using EXT19.13 following successful LVS.

I get this error at the end of QRC log:

I wonder why I get these errors?

Since posting the problem has gone away -  not sure what I did but glad its decided to go away.

Would be nice to delete this post.
