You have messed up your listening configuration by running listeners off both the RDBMS home and the GI home. If you do not know what you are doing, that is a bad idea. You need to decide what node listeners and how many SCAN listeners you want to run (probably three SCAN listeners and one node listener per node) and off what home you want to run them (probably all off the GI home) and whether to place them under GI control (probably a good idea) and configure accordingly.
