Hi,
Did you change some ACL access in the HikaShop configuration ?
If your account do not have access to filters, this item menu wouldn't be displayed.
If not, you could send us an access to your backend by private message and we would investigate and fix this problem for you.

By the way, do not send me private message, use the "contact us" form instead.
