Betaflight OSD not showing all data?

Hello,

I have a problem with my FPV drone. I converted a Tinyhawk II Freestyle.

FC Betafpv F4 V4 22A

VTX Succex 350mw Micro

RX XM plus

I configured an OSD in Betaflight, but it's not fully displayed on my headset. For example, I set it so I can see the battery level in the OSD. But the entire icon doesn't appear on the screen. After the flight, however, the correct voltage is displayed. However, I can see other elements in the OSD, such as the crosshairs or flight mode. I don't know what to do; it would be great if someone could help me!

Thanks!
