Hey I think I've done everything right but I'm having an issue where I have multiple upgrades (weapon level , 2, 3 etc) in the same button spot on my command center and the first upgrade works fine, but after that the level 2 upgrade doesn't show up, the level 1 stays there. Researching the level 1 upgrade again does nothing. Am I missing a command in either the ability or the upgrade so that the levels show up/disappear properly?
*edit
Figured it out just needed to use requirements.
