Razer Deathadder Elite on Synapse 3 (Macro doesn't work)

Hi, I just bought a brand new Deathadder Elite, I'm having problems with a macro option on Synapse 3 that worked perfectly on my old Deathadder Chroma with Synapse 2. The option "Play while assigned key is pressed", on Synapse 2 it used to work like this: while the mouse button is pressed, the macro would be executing but when you stop pressing it should stop. On Synapse 3 it doesn't work that way, it repeats the up and down of the key while the button is pressed. I want it to work like a keyboard key, when I press it hit down and when I let go it hits up and stop. The same macro configuration worked like a charm on Synapse 2 with Deathadder Chroma.
