Hi,
As explain, "HikaMarket front-edition" does not support the multiple vendor feature.
That's why the button "vendors" in the backend of "HikaMarket front-edition" should not be displayed (problem which is now fixed in the latest package).
As explain, if you want the multiple vendor feature, you should use HikaMarket Multivendor, otherwise you can use the "front-edition" to edit your products, categories and your orders directly in the front-end.
You can see the comparison between the different editions of HikaMarket here:
