The nTokenAction implements two token approvals, the nTokenWhitelist which is always used first, and the nTokenAllowance which is checked second.
If the nTokenWhitelist does not have enough allowance for the transfer, the transaction fails, even in the case where nTokenAllowance still has enough allowance.
Transfers that have sufficient allowance fail in certain cases.
Recommend that, instead of reverting if the nTokenWhitelist allowance is not enough, default to the nTokenAllowance case.
Something like this:
