Subscriber Role Users Seeing Other Admin Functions

I’m having a big, weird problem and could use some fast help.

Users that register on my site (through the WishList Member plugin) are given the role of SUBSCRIBER. This of course means they should have only access to see/change their profile. However, these users are also seeing other functions in the admin dashboard: any function that has a “Re-Order” option, they can see. So, when a subscriber logs in, they are seeing:
Posts (just the Re-Order drop-down), Contact Forms (a plugin – just the Re-Order drop-down), Promotions, Portfolio, and Slider (again, all plugins, and they only see the Re-Order drop-down).

Any suggestions where I can go to try to stop these tabs/pages from showing on my subscriber-level users? Thanks in advance!
