Multiple VAT condition on traderpass excise amount

I would like to post MIRO where traderpass excise is included.I have done all the process of genrating GRN till posting excise duty. My tax code contains two VAT conditions i.e. 4% & 1% it is calulating VAT 1% on excise amount but 4% VAT is calculating only on basic value

Kindly suggest
