Nope, missing and disappearing competitive career profile stats have been a bug since launch and the only thing the Devs have done is acknowledge that some console players have incorrectly merged stats a few days after launch day. Here’s a link to my post in case you’d like to read more about this issue: Comprehensive Thread Of All Top 500/Competitive Bugs. I’ve compiled a list of posts regarding similar bugs under: Incorrect Competitive Career Statistics Page.
As far as we know, the Devs have said they still have that data, but will not bring back those stats and will continue to hide the oldest competitive season’s data with the launch of new seasons. Assuming my math is right, Overwatch 1 competitive data will be completely hidden to players starting in Season 7 on December 19th. It’s all so frustrating.
