Oauth2 token not usable

Hi,

I have some trouble using Oauht2 authentication with Postman ( v5.3.2).
I’m using Azure ADB2C identity provider, and I try to get credential from it.
I could get my access token without problem, but after that, when I would like to select the token in the token list, I cannot do it.
In the screenshot below, I cannot select a token in the Available Tokens list.

Is it a postman problem or do i something wrong ?

Thanks
