Just putting this on the record. When creating a Gauge using percentages in Hosted Cloud, the "%" sign is being displayed in the labels as the escaped text value (%25) instead of human readable output (%). This is not user input - this is happening in the gauge generation process by Rollbase.
The values in the image below should have had the following labels 9%, 15%, 30%, 45% and 60%.
I confirm the issue - tracking defect as PSC00328479
