error when payout a vendor

-- url of the page with the problem -- : picton.place
-- HikaShop version -- : 3.2.1
-- HikaMarket version -- : 2.0.0
-- Joomla version -- : 3.8.2

Paying out my vendor, this error (attachment) was shown. After that, the bill to the vendor was built correct, but the open orders are still there

thank you, Jerome,

reinstalling HikaMarket worked without any problems and solved the bug in the backend. But there is still the paid amount shown as unpaid in the frontend.

greetings
Peter

Thank you Jerome,
the new release fixed it.
Now i found some new trouble: I cannot delete an order. I tried to delete an Order of my "test-user" L2H37. In the message you see, that L2H37 was changed to 237.
Hmm any idea?
