Undetermined modules in the admin panel

-- HikaShop version -- : 2.6.0
-- Joomla version -- : 3.5.0

Hello. The administrative panel in a large number of modules are automatically created type "hikashop module". Despite the fact that I have them periodically delete all, they are still there and there.

Turning a blind eye to it, I can not, because When they become very much, Joomla engine starts wildly hang in the administrative panel becomes impossible to work with menus and modules.

Modules are all exactly the same, unpublished.
