Troubleshot refiner gibberish

Question

I have a managed metadata column in a library, then our admin map it to a crawled property in Central Admin and ran a full crawl.

When I add the refinable property to Refiner, I saw the gibberish as below:

I wonder how can I troubleshot the refiner gibberish?

Thanks,

You probably mapped the managed property with the crawled property that contains taxId in its name.

You'll have to remap the managed property with another crawled property that does not contain the taxId in its name. You should normally have two of them as you can see in the screenshot above. The crawled property without the taxId contains only the display name.
