Hi Paulpaul, the issue you are experiencing looks to be tied to another problem that I see which is that an extra RT is being generated on the second page of your track table. When I look at your 2 last pictures, I see that the last RT in your style (on page 1) is the same RT that is on page 2. This is a bug that we have been notified about and are currently investigating but it is leading to another error when you then try to add your own RT. I think Pipeline may have experienced this same issue based on the image that he uploaded. The latest version will be released today and should include some fixes which may help improve your experience. Please let me know if the problem persists. Thank you for the great feedback!
