Grid and Bar/Beat Markers scrambled and disabled after using Beat Detective!!

[Robbry]

Hi, I would really appreciate it if someone could help me out with this issue.

During a session I decided to try "beat detective" to quantize a region. I'm obviously a rookie because I later realized that my Markers had been scrambled and I lost my bar/beat grid in "grid mode". Everything is off the grid now and it makes it extremely hard to edit anything. I've already saved it like this so I cannot undo anything. If anybody has any idea what I've done wrong or how to fix it, please let me know.

Thank you for your help.
