Note: Doc team updates the current version of the documentation and the
two previous versions (n-2), but we address *only high-priority, or
customer-reported issues* for -2 releases in support.
Describe the changes in the doc and link to your dev story:

1. - [X] Mandatory: Add the required version to the Fix version/s field.

2. - [X] Mandatory: Choose the type of documentation change or review.

• [X] We need to update to an existing topic

• [ ] We need to add a new document to an existing section

• [ ] We need a whole new section; this is a function not
  documented before and doesn't belong in any current section

• [ ] We need an Operator Advisory review and approval

• [ ] We need a z-Stream (Errata) Advisory and Release note
  for MCE and/or ACM

3. - [X] *Mandatory: *Use the following link to open the doc and find where the
documentation update should go. Note: As the feature and doc is
understood and developed, this placement decision may change:

• Published doc: https://access.redhat.com/documentation/en-us/red_hat_advanced_cluster_management_for_kubernetes/2.10
• Source: https://github.com/stolostron/rhacm-docs

4. - [X] Mandatory for GA content:

• [X] Add steps, the diff, known issue, and/or other important
  conceptual information in the following space:
  Add known issue under this section https://docs.redhat.com/en/documentation/red_hat_advanced_cluster_management_for_kubernetes/2.11/html/release_notes/release-notes#known-issues-applications

Title: Application topology displays invalid expression for Exists and DoesNotExist operators
Content: When using Exists or DoesNotExist operators in the Placement resource the application topology node details will display these expressions as #invalidExpr. This issue is just cosmetic as the expression is still valid and working as expected in the Placement resource. The workaround for this issue is open the Placement YAML to see the expression.

• [ ] *Add Required access level *(example, *Cluster
  Administrator*) for the user to complete the task:

• [ ] Add verification at the end of the task, how does the user
  verify success (a command to run or a result to see?)

• [X] Add link to dev story here: https://issues.redhat.com/browse/ACM-15012

5. - [ ] Mandatory for bugs: What is the diff? Clearly define what the
problem is, what the change is, and link to the current documentation. Only
use this for a documentation bug.
