This is happening with every export job I've created in v2019.  I specified a comma delimiter on the Configuration tab of VI.  My export files all have an extra comma at the end of each row.  For example:

AC,XXX01,2018,01,1A,2G,0,

PS: What's wrong with exporting with VI?

VI Exports are awkward and limited.  If a VI job works for your needs, great.  Other options (with some good alternatives listed already) are more flexible for sure. 

In addition to the suggestions others have posted, VBScript is effective too (through ODBC), with excellent control over the formatted output.
