When having Paylink window opened there is displayed such fields "Sum", "VAT", "Total", "Pay Term".
When I was testing this before all fields were in Lithuanian language, after developed wishes, fields language has been changed to English.

Additionally, when creating Invoice Email with paylink, we have in text button "Pay Now", this button also before wishes was developed for Paylink, it was in Lithuanian language.

If there is any setting where I can change language for this fields, please share them with me.
