Units still available after deleting equipment/unit files

[NETSCAPE]

I created some test units to get a feel for working with equipment.pzeqp via spreadsheet modding. The tests worked after exporting the data with the game editor to create the "units" file that the game uses.

After awhile I wanted to start over with my spreadsheet modding and make things nice and tidy and re-make/evaluate my new unit ideas. So I deleted the equipment file, my equipment spreadsheet and the units file. And I started over via backups of the original vanilla game files.

The problem is these units that I deleted are still visible in the game editor place units area as well as in the in-game unit purchase menu. It is driving me nuts. I've creating new and improved versions, but still have the old one sitting there starring at me...

Is there a game or editor cache file I need to delete or something?

thanks in advance

EDIT: Just changing the names of units creates an entirely new unit and the old unit remains in the game editor and in-game purchase screen...

EDIT AGAIN: At the very bottom of the Units.csv I found the duplicate units stacking up because I used a search feature in libreoffice. I deleted the rows, saved but the game editor won't launch and gives me an error. So if I can't manually edit units.csv. And my equip file editing > editor export function to create unit.csv wasn't properly... soooo yeah. what now?
