Marketpress adding a custom menu its which I cannot remove.

Hi

I have an issue with Marketpress where it keeps adding a custom menu its which I cannot remove.

It is a custom menu item navigating to 'Products'
and states pending.

The only way to remove the item is to switch off Marketpress. However, I lose all product related menu items and the offender returns immediately I switch Marketpress back on.

Thanks in advance

Stef
