Hikamarket Same Order Number for vendor (front end) and for buyer not the same

-- HikaShop version -- : 4.1.0
-- HikaMarket version -- : 3.0.2
-- Joomla version -- : 3.9.13

Hi,
I'm confused, as I find out, that in multivendor market vendors gets different order number, then order number is for buyer and in back-end.

Sample:
Buyers gets AP-00115, the same is in backend
Vendor in front end gets order number AP-00116

In hikashop / configuration / main / Order number format set AP-{id size="5"}


And Question about invoice number ->
For vendors in front-end system do not generate the invoice number. It is empty, just label.
In back end I tried 2 ways:
First in hikashop / configuration / main/ order / Invoice Number format entered AS-{order_id} and made that the each vendor do have their own
Invoice Number format , like Dangus-{id size="5"}. It won't work, the invoice number empty, when vendor try to generate invoice in front-end.
Then I removed any value in hikashop / configuration / main/ order / Invoice Number format and left only in vendor config page (hikamarket / config / vendors --> vendor options, but it won't work as well.
How to fix that?

Thank you in advance
Lina
