instrumental echo FLX 4

Good morning everyone,
I'm asking for a little help I think with a small 
problem...
I use Serato DJ Pro with a Pioneer FLX4 controller.
When using Stems, when I click on the 'Instrumental 
Echo' pad, the bass and drum pads are also 
automatically deactivated and I am forced to manually 
reactivate them.
Since I like the echo effect on the outgoing 
instrumental part very much, don't you know 
if it is possible to deactivate the automatic 
deactivation mentioned above? (basically I would like 
the same as happens for the vocal part, 
if I click the pad on the echo effect voice, 
the other pads remain active).
I hope I was clear, thank you in advance
