From memory, this is the same question answered in the past:

Top Trace Removes Bottom Trace? (ANSWERED)

Hi. I am running a high voltage 240VAC line from part to part and wanted redundancy by forming a thick trace (3mm) on the top layer and ALSO a thick trace from/to the same components on the bottom layer as well. BUT when I drag a trace wire on the bottom layer from the components that already have a trace on the top layer, the top layer trace is automatically removed and only the bottom layer trace is kept. Why is that and how can I run a trace from two components on BOTH the top layer and the…
