Error with TaxJar plugin when orders with decimal quantities are synced

I am receiving an error from TaxJar plugin, when orders are synced some of them are giving the following error: “FAILED: Invalid request sent to TaxJar. Details: amount must be equal to the sum of line items and shipping, excluding sales tax.” I notice that all the orders which fail contain products with decimal quantities (2.5, 1.25, etc). Is it possible that the Product Quantity is rounding in some way that TaxJar does not like? Are there any settings that I can specify to fix this? Love this plugin, thanks!
