Error: Missing name in the variation specifics or variation specifics set.

The multi-variation options are incorrect. Possible causes include:

1) The variation attribute name and option name are entered incorrectly.
There is an extra colon,
a missing colon, or
an extra space.

2) You are trying to revise variation attribute name in a listed item
* eBay does not allow changing the variation attribute names of multi-variation listings that have already been listed in third-party software. Users can modify the variation attribute names in the eBay backend and then sync them back to SoldEazy.

Solution:
If only one variation name is problematic, modify that single variation.
If all variation names are problematic, export the file to Excel, select the problematic column, and use the replace function to resolve the issue.
