1. Open the affected UI Component in the UI designer.
2. Observe the error message: "Unable to perform content Operation for user KC123XXABC in Client XXX".

• When creating a Custom Action CT (Change Transaction), a Stable Anchor is generated.
• A subsequent CT can reuse the same Stable Anchor.
• If the original CT is deleted, the Stable Anchor associated with it is also deleted.
• This deletion causes the error: "ButtonGroupAnchor missing in the UXView" during the merge process which in turn raises error in the UI designer- Unable to perform content Operation for user KC123XXABC in Client XXX

There are two options here to resolve

• Revert the deletion of the original CT that created the Stable Anchor.

OR

• Delete the subsequent CT that reused the Stable Anchor.
