WooCommerce booking removed from cart immediately when locale = "fi"

[sailinf]

I have encountered an annoying issue with with WooCommerce Bookings. When I set locale to "fi", the Booking is autoremoved from the cart immediately (and booking is impossible). When locale is set to "en_GB", everything works fine. This happens regardless of which locale is set to default so it is not connected to being default or not.

Here is a screencast test showing the issue: https://youtu.be/kmxHWFlJwME?t=2m1s

Any ideas? This essentially makes qTranslate+Bookings useless.

Did you try to integrate it: https://qtranslatexteam.wordpress.com/integration/ ?
Can you send us the plugin Woo-Booking?

There is not chance that I could do integration as just a regular site manager, so no.

Yes, I got it, thank you, I will try to reproduce shortly.
