Hi @objorkli

Thank you for reporting about the problem.

Workaround: set custom dataLabels.formatter. Demo: https://jsfiddle.net/BlackLabel/02rtqxp6/1/

Internal note: return H.correctFloat(amount * 100) + '%'; should be enough here.

return H.correctFloat(amount * 100) + '%'; should be enough here.

Yes, agreed.
