DLC cars missing from Career mode dealership - Microsoft Store - PC

Hi everyone,

I've been experiencing a persistent bug with DiRT Rally 2.0 on PC (Microsoft Store) where DLC cars and liveries do not appear in the Career mode dealership (My Team), making it impossible to use them in career championships or daily/weekly/monthly events.

My setup:

• Platform: PC, Microsoft Store
• Purchased base game ~1 year ago, then all DLCs separately, then GOTY Edition

What works:

• All DLC cars and liveries are fully accessible in Time Trial mode
• All DLC stages appear in Time Trial and custom events
• Colin McRae Flat Out Pack works correctly in its dedicated mode
• Weekly community events work, but only with base game cars

What doesn't work:

• DLC car categories are completely absent from the Career dealership
• DLC stages don't appear as career championship locations

What I've already tried:

• Full uninstall and reinstall of game and all DLCs
• All three in-game reset options (Reset Championships, Reset Progress, Reset Account)
• Tested with a second Microsoft account on the same PC — same issue
• Xbox App confirms all DLCs are installed and licensed correctly

I've seen other users reporting the exact same issue (thread: "DLC Cars not showing up as available to purchase in Garage"). This appears to be a RaceNet profile registration bug specific to the Microsoft Store version.

EA support confirmed they don't have backend access to fix this and suggested posting here. Has anyone found a workaround, or has this been acknowledged by any dev?

Thanks.
