Hi, Running version 4.59.4, clean install of wordpress with multisite, no other plugins, with TwentyTwentyOne Theme. When in Network Admin, Users I click “capabilities” to get the Editor page. The users primary role is “administrator” ( those it is to same for any role ), I see all the disabled check boxes for that role. I checkbox a new cap to add, and click Upgrade Network, it clears all of my primary roles caps but saves the new cap I selected. And my primary roles is now not selected in the primary role pulldown. If I reselect the admin role and click update then it applies the admin role to my user, but not for all sites. I can consistently reproduce this issue.
