How to use Loyverse POS and Zoho One Books Kenya with VAT Registration

I want to use Loyverse POS and Zoho One Books Kenya with VAT Registration. 

In this setting Customers are either VAT Registered or Non Vat Registered. 

I have a default customer “A Walk-in Customer” Non Vat Registered both in Zoho Books and Loyverse. 

When I create a Zap the Zap Obtains a Receipts Update from Loyverse then is supposed to Create a Sales Invoice in Zoho. The error occurs at the VAT Treatment variable and Tax Treatment Variable. 

In Zoho the available options for VAT Treatment are 

1. VAT Registered (doesn’t work as an option in Zap)
2. Non Vat Registered (doesn’t work as an option in Zap)
3. Non Kenya (doesn’t work as an option in Zap)
4. Leaving the field blank leaves no error message

In Zoho the available options for Tax Treatment not totally sure but may be any of the below 

1. Out of Scope
2. General Rate [16%]
3. Tax Exempt 

or 

1. Taxable
2. Non Taxable

Non of these seem to work in the Zap. 

Please help. Who has an already working Zap?
