I reached Gold V (Solo/Duo SR) in Season 8 but I do not have the gold border

I reached Gold V (Solo/Duo SR) in Season 8, but now in Summoner’s Rift, Draft pick and Coop-AI I do not have the gold border. I only have a silver bolder (For SR ranked flex I was silver in S8). I do have a gold border for ARAM and ARURF, and SR solo/duo rank though.
