Default currency on load is wrong

Hello there!
I already created this topic today, but can’t see it on my topics page, so I’ll duplicate it.
When I open the page, the default selected currency is wrong here https://prnt.sc/flY_r5ZCOwcI. Here are the admin area settings https://prnt.sc/JRxLrRszmfFa, so the default currency on load should be USD.
Can you pls check why it happens?

Also, what I noticed, is that when I try to change the currency, it doesn’t work – just reload the page with CHF selected again. Maybe you can advise what is the problem here.

Thanks in advance!
