iperfspeed confusion

I've had iperfspeed installed on several nodes and it works.  However I decided to fool around with the new checkbox in advanced settings on 3.24.6.0 and see if that makes the old package obsolete.

I managed to confuse myself quite nicely, so some questions.  Simply checking the box in the advanced settings does not make an iperfspeed link on the node, and I could not make a link to the pre-installed package.  I used port 8080/iperfspeed like with the previous packages and it did not create a link.  Hmmm.

Then I unchecked the settings slider, and relinked to the existing iperfspeed lua package and it came back.  However there were only a few nodes available to test.  If I left the package linked but then went back and enabled the advanced settings slider, now I have a large list of nodes to test with.

I see on another node that I have 3.24.6.0 on, I can use the slider.  That node does not have a linked instance of iperfspeed.  However if I go back to my other node with the package installed that remote node now shows up in the list of available nodes to test.

The question is ... shouldn't I be able to move the slider, and then advertise this as available so I can access it from that node?
