Which travel button are you referring to? The one in the cockpit?
Try hard refreshing your browser and clearing cache.
Please provide more details like what browser/OS/etc.
Try multiple browsers; I have tested against Chrome/Firefox/Edge/Android Firefox/Android Chrome
Never Mind- Reproduced it in IE11. Use workaround below temporarily or consider switching to edge/firefox/chrome. Will work out a solution.
As a temporary workaround here are the pages that it can link to; you can visit them directly if you are still having issues.

http://www.swcombine.com/members/cockpit/TravelFrames/index.php?tft=undock undocking -- visiting this will usually immediately undock you
