Ambiguity in pin names of NUCLEO-L4R5ZI

I am using NUCLEO-L4R5ZI in my project and I found the pin names ambiguous in the CN10 header. For each of the mentioned pin names (PE_12, PE_14, PE_15, PB_10, PB_0) there are two pins allotted, this means I can use only one pin of the two pins with same pin name in my application. Please help me in understanding this.
