Input fields in VFB use comma when my system uses period

There’s something that’s been bothering me with VFB. The input fields in there use comma when my whole system is set to use period. Why is that and can I fix this? I’m using Max 2020.1 + Vray Next Update 2. Thanks in advance!

What are your Windows regional settings?

Best regards,
Vlado

My regional settings are as follows:

Format: Bulgarian (Bulgaria)
Additional Settings: decimal symbol is period
Location: Bulgaria
System Locale: English (United Kingdom)

I forgot to mention that input fields in Max itself use period so looks like it’s isolated to VFB only.
