Not showing any progress for event decal in which requirements have been finished already?

I’ve already finished playing 3 games with above 70% activity for the PRC event decal, and even if I didn’t finish the requirements, why is it not showing my progress? I’ve encountered similiar issues before but I didn’t mind at the time however I like this decal very much and would like to obtain it, all my friends acounts show a progress bar of 0/3 while I’m the only one that shows no progress even though I’ve already finished 3 games with the requirements met.
