Aftermarket LED tail light issue

Hi everyone, I have just purchased a set of what seem to be good quality ebay aftermarket led tail lights, I currently am running into the issue of the new tail lights, if you unplug the left turn signal, the right side will act correctly when using the turn signal to the right, if the left side is connected, and so is the right side connected as well, both will flash at the same time, no matter which was you flip the turn signal, both led tail lights have ballast in them, this is the second one of the aftermark tail lights that are doing this, any advice on where to start?

Thank you.
