1. What's the firmware are you using on your T22P?
2.Could you send us the words that you filled in the Label and Display name? So we can test at our side.
Thanks.

I put this name in the Label and Display:

Лидия Вуколова

The firmware is 7.70.0.140

But the strange thing is that yesterday, about a day after this happened, the display is ok again.

When the above issue happened, I also had an issue with another telephone on the same local subnet, a Yealink T46G. When I called this telephone, and I answered it, the calling telephone heard a low-frequency sound that made it difficult to hear what the other person said. I thought this had nothing about this issue, but when the display issue disappeared, so did the sound on my T46G. Very strange indeed.

Best regards,

Ivan C Myrvold
