Sidekick links not working

[TchakamauRa]

Hi,
I installed Sidekick to use the links suggestions, but for me they are not clickable.

If I move the cursor from the popup the links will disappear. You can see also how it's interacting with the text below (highlighting it) and not the popup. So my link suggestions are not clickable, like yours seem to be in the demo.

Do you know why that is? Would this be a Sidekick or a system issue? I tried searching for people with similar problems but find none. Thanks for making Sidekick, by the way.
