I can't make this happen. Was it showing up without the "year" filter?
By default the year filter should be there and it should show "latest". If it's not there, then it should show multiple years, I suppose. But it should be there!!
I can still make this happen for ex if I X out the Year filter and then try to bring it back (it might be only on company pages now?). https://wikirate.org/Jiujiang_Janny_New_Material_Co_Ltd?filter%5Bnot_ids%5D=&sort=bookmarkers&filter%5Bstatus%5D=exists&filter%5Byear%5D=latest
Yeah, I'm seeing this, too.
fixed!
