We're aware of an issue where, visually, your Bars in the Lobby will appear to match the amount you gained in a Competitive/Arena match instead of your total amount. Going into a non-Arena game should still show your total Bars available.
When in Arena, you don't have access to your persistent stash of total Bars and instead have 50 Bars available to start each match with. Hope that helps!
