False "No ventures in progress" when in Diadem

I'm pretty sure this is rather new. When I'm in Diadem, I often used to check the venture timer to figure out if I do one more turn or leave the Diadem. The Timers show false info about retainer missions.

Date & Time: Feb 13 2022, 16:28
Frequency: always (could reproduce it)
World name: Twintania
Character name: Qujah Lipuya
Retainer name: all my retainers
Class/Level: BTN 90
Area and coordinates: The Diadem

Steps:
1. Send your retainers to ventures
2. Enter The Diadem
3. When in The Diadem, check Duty/Timers.
4. The Ventures timer says "No ventures in progress", even when there are ventures in progress (see first picture)
5. Only if you click on that false information, it shows "Time remaining" (see second picture)
