I cannot reproduce this - and obviously noone else so far either -, is there anything special, you using a special OS or something? If not, I'd reach out to Steam support, I don't think there is anything we could do.
Oh, so it indeed was that - I assumed you had already checked that given you said that in the opening post. "None" means you are not using any beta branch, which automatically means you get the normal released version, currently 9.5. Glad you got it solved :)
