Cannot record in singleplayer mode of Q3TA

[quake1982]

I recently found that no automatic game recording by clicking "YES" of "Record Game", when I started to play singleplayer mode of Q3TA. It's very odd that this is totally functional on "Tournament" mode, but not on the rest team-based modes, such as "capture the flag". In order to record games e.g. capture the flag, I have to get into the game, open the command console then type "/record" to achieve it. I use the vulkan mode, BTW.
