I think it is not an issue.
The textTpl is used to calculate the needed addtimedisplayWidth to show the addtimedisplay-Text.
With "00:00 - 00:000" you can set the max. of width for all values (begin - end time) to get the best calculated needed width.
Perhaps the width was sometimes to small, so the textTpl was added by a next 0. ![]()
