Bing Data Error - Filters

I've been pulling data from Bing Ads via Supermetrics without issue for a year or so, recently i've noticed a failed query, and on closer investigation the data is incorrect when filters have been applied.

I am trying to filter different campaign names to segment costs, clicks and impressions but found that while some return data it is too low, some don't return any results and when multiple filter combinations are added it is massively overstating the impressions.

I have deleted all queries, re-set them up, logged out of the Bing link and back in again and nothing seems to be helping.
