Can't click the blue send button when sending to another wallet. Token value disappears in the sending process

Hello. I struggle to send tokens to another wallet.

They show up in my portfolio, also with the value (1).
If I click on the tokens, they also show up (2).
If I click further to send, they suddenly don’t appear in the wallet balance (3).

Then, if I type the wallet adress I want to send them to, I’m not able to click the blue “send” button. I have the latest version and resetet three times already.
Also I can’t swap them on uniswap, since the value isn’t recognized there too…

What can I do?
