Version

Bot Framework DotNet SDK 4.22.4

Describe the bug

If I create a new message activity and label it with "AI Generated" and "confidential," and then update this message again with UpdateActivityAsync in the second step, the labels "AI generated" and "Confidential" disappear.

The issue also occurs when the update activity has the same entities as it did during creation.

To Reproduce

Steps to reproduce the behavior:

Create a new message activity with the following code:

var activity = Activity.CreateMessageActivity();
activity.Text = "Insert text here";
activity.Entities.Add(new Entity("https://schema.org/Message") { Properties = JObject.FromObject(new { additionalType = new[] { "AIGeneratedContent" }, usageInfo = new { name = "Confidential", description = "Contains Sensitive Information" } }) });
var response = await context.SendActivityAsync(activity);

The message has the following labels:

Update the message with the following code:

var updateActivity = Activity.CreateMessageActivity();
updateActivity.Id = response.Id;
updateActivity.Text = "Insert text here (update)";
updateActivity.Entities.Add(new Entity("https://schema.org/Message") { Properties = JObject.FromObject(new { additionalType = new[] { "AIGeneratedContent" }, usageInfo = new { name = "Confidential", description = "Contains Sensitive Information" } }) });
await context.UpdateActivityAsync(updateActivity);

After updating, the message no longer has any labels - except of the "bearbeitet" (edited) one..:

Expected behavior

UpdateActivityAsync should not delete the labels.
