Hi Pradeep,
The reason you are getting mismatch in MDM Multiple/exact matches with the data may be because of Duplicate records existing in MDM system. I hope if you do a match and merge the mismatch issue could be resolved. After import you have reported that the record count is 221. make sure that the search criteria you have given for all those records is "=" and if more than 1 field is used in match criteria then all the fields should be given respective value and then you perform the search.
Thanks
