Support for Multipress

Hi team,
First if all you’ve created amazing plugin. I was fascinated by the details and professional approach in admin area.
So here what struggles me and I will appreciate your quick response on this:
? We tried to create vehicle categories and no matter how many time we enter information it doesn’t show in admin area and respectively when we try to create vehicle in our fleet
? Same thing as above happens with prices. I enter prices and when I click “Confirm and Add” it gives me confirmation but the price scheme is missing
? Next I need to know what is the policy for multipress websites. Currently I have one website per language (Bulgarian, English and Russian) and one site only for redirect traffic to appropriate version. So If I purchase today your starter plan is it cover my topology or I need to purchase it 3 times. If you have a minute here is the prototype – https://mrentacar.bg/bg/

Looking forward for your answer
Best regards,
Dimitar Dinev
