Assuming you completed the 15 minimum games requirement and had at least one rerank for both Open Queue and Role Queue to be considered active, then no, this seems to be a bug as you should have received competitive titles for both gamemodes and competitive points based on your highest final rank division. Fortunately, receiving only the title for Open Queue but not Role Queue, and vice versa, is a documented bug, which you can read more about under the subcategory: End-Of-Season Competitive Rank And Rewards. Here is one of those posts: Didnt receive Ranked Open Queue Title, only Role Queue title. There are also several much larger threads about missing competitive rewards in general as well, which are all listed at the top of that subcategory if you would like to help bump up those threads too. Hopefully with enough traction the devs will implement another retroactive fix similar to the ones in Season 5 and 4 and give us all the rewards we earned…
