i am facing the same problem, already made an entry in the community:
Ive tested a lot of scenarios, so far what i can tell is, that with internet Explorer this doesnt happen. With chrome and Firefox it does.
As a workaround, there is a table extension that support Hyperlinks, its called "Simple table", thats the only way i got it to work in Chrome.
I also made an Open Case in the Qlik Support, as i think this should not happen, but it is still in investigation.
