The following technical issue has been resolved in GMG OpenColor 18.104.22.1686. Please note that the list describes the problem, not the solution.
OpenColor separation rules removed by update
After updating OpenColor 2.1.x to 22.214.171.1245, any previously calculated OpenColor separation rules were no longer displayed correctly in the user interface. Instead, all colors were listed as "Calculation Pending". The issue only affected the display of OpenColor separation rules. Previously calculated information remained available for internal processes (e.g. calculating new profiles), as did any calculated profile.
