Hi - I have an attribute table in which I have a field 'Period', within that field is 4 values 'Neolithic', Bronze Age', 'Iron Age' and 'Romano-British'. I selected unique values and 'Period' on symbology, as well as 4 classes, and yet the symbology is showing multiple colours/symbols duplicating my periods - I have attached a screen grab. Any thoughts welcome!
