Disable Module Under Product Display ?

Hi Nicolas,

I have a module on left col named as "you might interest", it is actually a "related product" section in 1 col x 4 items (please see picture).

Then I found there is a similar module came out from bottom of product display area, also names "you might interest" in center align (1 col x 4 items vertically).

I don't want this bottom module to show up, but forget where to disable it?

I didn't create this module, have checked through all modules created.

Oh, after disabled "Modules under the product page", it disappeared from bottom of product page, but found the module in the left column don't working well now - it's don't show related products but everything randomly?

Or, this has to create individual module for each category?


Thank you!
