Recommendation tool Unable to 'Save as' a Collection from within the Advanced Search feature

[ben_mrm]

Hello,

I'm running into issues when trying to save a collection that I built using the 'Advanced Search' featured within the Adobe Target Recommendations tool. I've narrowed down my products list by applying a number of search rules but when I click the 'Save As...' button, the Collection and Exclusion options are grayed out. Any ideas why?

Please advise.

More specifically, this seems to be occurring when I try to incorporate a 'value is present' or 'value is not present' parameter into my search. Also noticing these are not options under the collections tab themselves. So wondering if there is a disconnect between the Advanced Search capabilities and Collections.
