Invalid xml: line 64 schedule hp state code

Hi all

I am trying to upload ITR2 XML during which I am getting this error

The XML schema is invalid. Please upload the XML in the correct schema.
At line number 64 : invalid content was found starting with element 'ITRForm:scheduleHP'. One of '{"https://incometaxindiaefiling.gov.in/master":StateCode}' is expected

I checked the state code under schedule HP and I had selected the correct one: 19-Maharashtra.

Can anyone please suggest any possible solution?

Thanks 

Ram
