Just FYI, the past tense of "strike" is "struck", not "stroke". It could be argued that it should be "stroke" to parallel words like "break-broke" and "wake-woke" but it's not. English is weird. (And the past tense of "hike" is "hiked", not "huck" nor "hoke", which aren't words at all [UPDATE - turns out they are, see child comment from u/GrinningFool], but they probably should be.)
“Struck” is the general past participle of “strike", “stricken” is a past participle available specifically for the sense of removing from a list (but the general form “struck” is also correct and often used for that sense, too.)
It's not that narrow - e.g. "was stricken by a sense of foreboding"
You also would say panic-stricken, not panic-struck.
Agree it's not universal though, helpfully, and sometimes is it "struck" in non adjectival past participle.
But not in the OP case, I think (much like striking off a list, striking off a sign). I probably should have mentioned that it wasn't universal for struck though.
