It seems there is an issue with this tag. I cannot clear after tool is removed.
Here are the data sent from adapter:

agent reports correctly for the current tool = 71893832

When the current tool is removed from the asset agent still report the current ToolAssetId which does not exist in Tool Assets any more.

Thanks
