Gate auto loads with loop UPDATE : sample

I Just wanted to test my old vintage TS9 to answer Mat's post and also compare its tone to the stomp box equivalent..and doing this I found something weird ...as soon as I switch the loop ON the noise lowers like if the new gate stomp gets on ..is it me or

UPDATE : Sample below

My old box sounds better than the equivalent ..100% sure that some gate switches on as soon as loop is selected..I'm going to check if it happens with loop post amp too

Happens with loop distortion post amps too..the two other loops are unaffected by this..Pre amp it affects all 3 loops types
Anyone can confirm ???

So anyone performed the same test ?

So here is a file that shows this bug I got..High gain rig loaded with Zero gate anywhere..Stompbox B is loaded with Loop distortion and a simple patch cable is plugged from send to return
At first the stomp is off..you can hear some slight noise from the profile,I then play a few chords and the noise is back again..then at 18 sec I engage the stomp (the loop) and listen how it becomes silent..I play a few chords again and then stop and still it is silent
IMHO I have the 2:1 gate loaded at the same time when I load the loop
