makeitwork101: Like rich2005 said, there is a checkbox in the Threshold dialogue that says "Merge filter". If you check that, the filter will merge down automatically like in GIMP 2.10. And GIMP will remember that checkbox setting, so you shouldn't have to choose it each time you use the Threshold filter.
