Zapier Merchant Fees

JKCWS

So in zapier, I have created a zap that imports all of my stripe transactions into a money in transit account (for a different online store not my wave invoices). The zap has the option to select the field for merchant account fees, and parses the data properly.

For some reason the transaction created in the wave side of things does not use this data and split the transaction (like it does for the wave invoices). Any ideas on why or if there are further configurations required to achieve this.

I really dont want to be manually splitting them all, especially when the data is there.
