Scenario
Custom Field are being renamed after Managed Bundle upgrade when checked on the system Notes but is set back again to the previous name after the upgrade.
Solution
- The rename is an expected behavior when an upgrade of the Managed Bundles occur. For example, if the Custom Field named "Sample Field" is from a Custom Record associated with a Managed Bundle, it will be updated to "Sample Field (2)" and will be set back again to "Sample Field" after the updates are done
