Tableau does not count all records

Question

I used wc -l file.csv to count the records in a tab-delimited file. Shows 127992 .

Connect to file in Tableau and it shows 63k records and some change. OK, so I check for blank IDs in the source file:

• awk -F'\\t' '!length($1)' file.csv
• awk -F'\\t' '!length($1){print $0}'
• awk -F'\\t' '$1 == ""{print $0}'

In no case did it expose a null or blank ID, which would be very low probability as the database this is pulled from doesn't allow this to be null. Trying to figure out, in what use case scenario would you want your software to discard half the data?

In Tableau, I create a calculated field, wondering why this would be necessary, but OK: COUNT([Itemnumber])

Keep in mind, I double-checked to make sure there were no NULL values and I get: 63,756

I'm used to Unix and new to Tableau so what am I missing?

Sample rows from file:
