Looking at the negative value I'm thinking it is showing my true sMerit balance if I weren't a source. I had 1000+ unspent "earned" sMerits and assuming I've given away 7000+ "source" sMerits the result would be -6000 which is what shows up...
Numbers do not add up in my case.
I had basically zero unspent merits, I got 18k merits, while I sent 60k in total.
The negative number was -30k.
I have been restored, anyway.
