Historian Quality Code 1,073,742,080 (1073742080) - How to filter values with `Uncertain` quality

On a few different occasions I have run into a strange quality code on my historical data.

The code is 1,073,742,080 (1073742080).

In a related forum thread I found.

Indeed the hex value of 1073742080 is 4000 0100 and the hex value of 256 is 0100 so this is arguably a value of 256 (uncertain) with one higher order bit set.

While I don't know exactly why I am getting this quality code my more pressing need is how to eliminate these apparently "uncertain" values from inclusion results a tag history query (system.tag.queryTagHistory). The function does have a ignoreBadQuality parameter but when this is set True is does not filter out the Uncertain quality values.

Is there a way to filter the uncertain quality values as part of the tag history query?

I have custom aggregation functions to find the change in a counter value between intervals and the erroneous values are messing up the algorithm.

UPDATE
Looks like the ignoreBadQuality may actually filter out the Uncertain quality values. In my data I had an anomalous value that was actually marked with "Good" quality and that is causing the issues I was attributing to the "Uncertain" quality values.
