Delete broken reference equation, meanwhile no equations left

Hello,

To make it easier to update/change our model i have made a lot of references from top to bottom. Recently i had to change the document names.

As a result i got 1 broken reference (not that exciting). But now each time when i pack and go, solidworks wants to bring a none-excisting assembly. It name got changed.

I would like to delete this reference to ensure all errors are 0.

My issue: The reference is hidden in Equations. Somewhere solidworks is still using the "old" name. I deleted all equations, but still solidworks keeps telling me there is an out of context error in the equations.

I added a screenshot, anyone can tell me how to delete this reference?

Thanks a lot!
