Check your GEDmatch settings

If you have uploaded DNA kits to GEDmatch please check to make sure your settings on the GENESIS side are as you would like them.  If you have uploaded duplicate kits, the software that they are using seems to mark the 2nd kit as the duplicate.  PLEASE make sure that the 2nd kit isn't the only one you have designated as Public because doing so will keep you from showing up in the One-To-Many Reports of your matches.  You can check the status of any kit by using the DNA File Diagnostic Utility located on the Genesis page under DNA Applications(see image below).  If that is what you want to do that's fine of course but if that was not your intention you will need to modify your settings.

You can change the status of your kits at any time by clicking on edit(the pencil image) beside the kit # and name and then selecting Yes, No or Research for that kit.  Be sure to click on change after any modifications.

This happened with my cousin's kit.  Neither of her kits were showing in the One-To-Many Reports of her half brother, or any of her other matches.  It may not be obvious to the manager if they only view that Kit's One-To-Many Report as they will see all the others they expect when running it for that particular kit.

If you have taken an Autosomal DNA test and haven't yet uploaded to GEDmatch Genesis please consider doing so if you agree with their User Policy.  We have all of our family DNA tests there and have also uploaded or tested at FTDNA & MyHeritage.  I have two tests at FTDNA that aren't at AncestryDNA but they are at GEDmatch GENESIS & MyHeritage.  I know I need to test at 23&me eventually when it becomes financially possible.
