Facet not applying on certain results

We are using the free/express edition of CoveoV2 for Salesforce using Visualforce pages/components.

Package Version: Coveo for SalesforceV2 - 2.48

Issue: Certain results are always appearing if:

a) filter expression matches (expected)

b) facet does not meet criteria (not expected)

Scenario: Facet value "Cloud" when selected still shows Result_A which doesn't have "Cloud" in the associated facet field. URL: #t=All&sort=relevancy&f:@SfProvider_Filters__c=[Cloud]&f:@SfProvider_Filters__c:operator=or

Notes:

1) Went to Network>V2 and was trying to discover the reasoning:

- None of the results were marked as an isTopResult

- isRecommendation is true on the items that seem to be returning.

2) Results are still respecting:

- sharing model

- objecttype filters (tab)

We had a similar issue in the past, noted here. I reviewed and believe that the main difference is that previously results outside of sharing/permission model was appearing. Now its specific to Facets criteria not being applied for certain records?

I guess my question would be do results with: rankingModifier: is "Reveal ART" that are boosted by Coveo's Automated Relevancy Tuning ignore facets? If yes solutions? If no any suggestions on how we should move forward with our debugging?
