// Edited: ..check your Unity/channels/etc preset files for errors ?
Or delete a map from the cfg and then replace it, hopefully causing the export preset to re-write itself.. :/
Honestly, I don't know why these files aren't just human-readable / xml. #ffs
I supplied this answer before I thought about your reply.. I was eating lunch and on phone at the same time...do forgive me.

1. If you're using a custom shelf path, then check your custom shelf to see if there is an "Export presets" folder with files..(as seen on right side of image).
2. If you're using the default shelf, then check the default shelf for this DIR and files.
■ 3. Check the install path(I used default install path for 2017.2), as shown in the image.
If you find the export presets folder to contain the presets, then copy them to your shelf.

I could zip up the DIR an files for you to download and add, but I am not sure what version you're using, nor how Alleg. would react to me helping in that way(various variables/scenarios).
