Shotcut doesn't find all my trackers

What is your operating system?

What is your Shotcut version (see Help > About Shotcut)?

Can you repeat the problem? If so, what are the steps?
I tried adding moving text to a video using motion tracking. Worked fine in the first part of the video. But when i try doing the same thing after the third cut i made, it doesn’t find all my motion trackers (I named them from Tracker1 to Tracker28). This wasn’t a big deal before the second and third cut because it finds tracker 1 and 2 but not tracker 3 and 4 which i need after the third cut…

Best greetings,
Thank you in advance
