Not sending to Transmission

[PatrBal]

Hi,
I am trying version 2.3.1 in Tampermonkey on macOS Safari. I am running two different instances of Transmission on two computers in my local network. I created two corresponding profiles. In each profile, the host is set under the form:
http://192.168.1.24:9091
using the local address of the corresponding Transmission instance.
In both profiles, Test client answers Client seems to be working.
Now, when I click the XST button on a tracker (tested with two different trackers) a pop-up window shows up, asking to chose between the two different profile. When I click on one profile, the pop-up window disappears, but nothing else happens. In particular, the torrent is not sent to Transmission. My two profiles refer to a Transmission instance running on local machine and another instance running on a remote machine in the local network. Any idea?

Same issue here with Tapermonkey. It works with Violentmonkey though.
