Negative balance on blockchain wallet and seller can't see my payment (picture)

[checkm8]

I'm wondering whats wrong with the middle post in this picture. The recepient claims they can't see the transaction and if you take a look in the Balance column there's a negative figure there. It does have over 150 confirmations and I can't find any doublespends anywhere.

Requesting some assistance here, thanks very much. How can the balance on a bitcoin wallet be negative? And would this make the recepient see this as a non-transaction?

No clue, maybe an address or a TX id?
I could probably find it, but Im to lazy today and you want help so you gotta provide at least some info.

A more general answer would be: its a bug.

Send the person you are dealing with a signed statement with your address and a link to the transaction using a different Blockchain explorer
