When using numeric variables in data links, the units are also passed

I am using Grafana 9.5.2
I need to create a data link on a bar chart to an external website, but when I pass a numeric tag field the unit is added at the end. I first saw a “%” added and then I changed it to “Percent” to verify. This looks like a bug because it not only happens when I use ${__data.field._value}, but also for other numeric fields. Tried to pass the field as string by adding quotes, but those are being passed to the URL as well.
Please advise.
