I don’t know what the problem is yet. That’s why I asked what kind of fields are not showing the correct values. Is it all fields or just some fields?
For example, a link field stores a serialized array. Altering the value of the link in a text file and then importing that into the DB will likely break that field. Serialized values need special handling. I generally import the db directly and then use this tool to make updates https://interconnectit.com/search-and-replace-for-wordpress-databases/
