Hello folks
I have also taken a close look at this and I think we are hitting a race around condition that is dependent on the order the triggers are processed by the template and the automations. It seems that by the time a template trigger is processed the input booleans may (or may not have changed). In addition when the ‘reset’ automation is processed it launches several triggers (start/stop and tactic) into the template which will be processed in due course (with no guarantee on the order). This is also compounded by the tic tac triggers that can arrive during the reset process. I added extra lap entries and observed up to two residual tactic triggers processed after the reset started (one in mid flight, one triggered by the reset automation).
I tried adding a wait on trigger for the reset process (triggered from the “00:00” status of the stopwatch sensor but it wasn’t quite there. I also considered a ‘resetting’ state to allow all the trigger to work through.
Below is my version of the code which takes account of the trigger type inside of the template as well as extra checks on sensor attributes. I looks like a bit of overkill but does seem to work. Ideally the template code would only use template variables and trigger details (to avoid scheduling race around issues), but did not succeed.
The code seems to work for me so try out and see if it works for you.

essentially if you start the timer and then reset it twice it shows 0. If you then wait, for example 1 minute and then toggle TicTac, it will switch the stopwatch to 1min. If you toggle TicTac again, the stopwatchwill show 2 min and then 3 min. Every TicTac toggle will add time to the timer and that time is exactly the time that passes since you last started the timer. Resetting does not change anything here. I mean you can reset the timer and start it and it will run but I mean that the TicTac is somehow linked to the time that elapsed since the last toggling of the stopwatch start.
