Virtual Agent error when using topic picker "Your test phrase triggered a different topic"

[Ryax]

I have an issue with one of my Virtual Agent topics whereby when the topic is selected from the topic picker an error appears as below:
"Your test phrase triggered a different topic. Go back to the NLU Settings tab and make sure this phrase is tied to the correct intent."

Whereas if I try to access the topic by using NLU and typing "Speak to a Service Desk analyst" (the same as the title used in the topic picker) then it works without issue.

I have checked the NLU intents for this and other topics and I cannot find any other topics that have anything remotely similar. When I also use the 'Test model' functionality within the topic the phrase "Speak to a Service Desk analyst" only picks up this topic.

Can anyone help me make sense of the above error and what I need to change to get this working?

Thanks

It did not work for me in the designer but when I tried to test it from portal, it was working fine. Not sure why this error is only on the virtual agent designer when we click on test.
