I don't have a solution but unfourtnately a similar issue. I can't post hyperlinks in this post but I posted a new thread regarding this in the forums. For us, its working in 13.32.2 but in one of the versions after that this issue is present, in our case is Swedish and not Finnish.
I will look into this. thanks for bringing this into our attention
In Commerce Variation validation there seems to be something changed. We are getting an validation error when editing Variation properties in Commerce with Finnish UI language.
Vähimmäismäärä = MinQuantity
Enimmäismäärä = MaxQuantity
Varasto = Inventory
Error message = "The field value must be a positive number."
Same problem occurs when programmatically saving changes to variation and context language is set to Finnish. Works fine with English.
Commerce.Core version 13.31.1 this was working but now in version 13.32.6 it's not. Could this be a bug in Commerce?
