Workflow issue : seller can’t receive several orders of differents users

Hi,

I use Microjobs Theme V8.9. I have a blocked issue with de workflow better seller and buyer.

For eg :

User1 is a seller and created a listing1 with Availability field : Always available
User 2 buy listing1 and after user 3 are buy this same listing1

User1 receive notification of email from the first buyer : user2 but no receive notification from the second buyer : user3

When user 3 go to listing1 the workflow is not display
When user 1 go to his lisitng1 the Workflow section/tab is always displays even if the work is completed.
When user 2 go to listing1 Workflow section/tab is always displays. If he click on the other “listing” section/tab he can see the listing and click to buy button. But nothing is happening and user1 don’t receive email

In admin area>ordermanagement and in the user1 seller dashboard>My jobs we can see Awaiting Work Done (1) (order with user 3) and My Completed Jobs (1): order with user 2)

I do a lot of tests and I have I noticed that if the seller sells his product once he can’t receive other order by all buyer. His listing is blocked because only the first order workflow display.

what is the normal running if seller receive several order of different users in the same time ?
Anybody meet this issue ?

Thanks
