Description of problem:

the version in Firefox is showing bad (incorrect) data (specifically, the "null" entry for "Start date" , and as a result the web UI for enabling/disabling the Sync Plan does not work.

In Chrome, the "Start Date" field has valid/correct data in it (a "Start Date" nearly 1 month prior, June 10, 2022), and as a result the UI to edit the 'Enabled' field works correctly.
