Does anyone else have filter-related issues in Delve?

I use custom loot filters created with FilterBlade. They're fantastic.

However, I've just discovered that they don't work properly in Delve, at least for me.

And it's not an Area Level issue. I'm at delve depths where the Area Level is 83 (the same as T16 maps).

A clear example of this is gems with Quality. I've adjusted my filter to have a lower threshold than Neversink uses for "high quality" gems, down to 10%. In maps and story zones, this threshold change works fine.

But in Delve, it seems to be using the non-customized quality setting (14% for the Strict version, which is what I use).

Now, it's possible this is related to the Map Reveal bug, which does eventually kill Custom Filters. But it's weird to me that the custom filters are working in all zones except Delve.

Anyway, I was wondering if anyone else has noticed this problem, or has a solution.

Thanks.

On standard, I'm running delve nodes around levels 70-80 with strict filter from filterblade and saw the same thing. Custom filter shows way more items than built in NeverSink.
