thats because you are setting the tank to output mode after rotating the switch, if you have 2 tanks, 1 is the "harvester" with the blue dots at the top, the second one, the "consumer" if set to the orange dot will output the liquid from the harvester to any connected waterprrof pipes at the consumer end

this isnt a bug, that was an intended mechanical design for use with liquid harvesting
