Clicking on "Remote Controlled" moves to next slide

I want to host a webinar and give each panelist remote control while they present. The problem is, once I give somebody remote control, when I click on "Remote controlled" button, it doesn't open the menu but moves to the next slide. Only the second time when I click on Remote controlled does the menu with Stop Remote Control show up.

I'm on Mac and Zoom version is 5.10.4 (6592).
