The timing tracks below are both imported from the Wizards in Winter .xtiming that is under xLights\Tools\Download Sequences/Lyrics.

In the first timing track below, I can select the area between two timing marks and add effects.

In the second timing track, I can only select the entire song (technically I can select the area between 2 existing effects, but I can't select the area between 2 timing marks).

That means I have to disable that timing track to be able to add any new effects, otherwise they'll always go to the beginning of the row.

I've looked for a setting on the timing track to see what makes them different, but can't find anything.

Does anybody have an idea what setting could make a timing track behave like this (and how to turn it off)?
