Can't Discharge Ship

icarussurvivor1

I'm trying to discharge one of the ships from my Starships roster (not my Dry Dock) but for some reason I'm not allowed to do it. Whenever I hit the "Discharge" button the typical prompt comes up, but after typing the ship's name the "OK" button is still grayed out. I've made sure that the ship is not my active ship, I've checked and double checked the spelling and spacing, and I've done everything possible- but it won't let me get rid of that ship.
