HOTSPOT - place hotspot rules here

What makes RouterOS alone create as many rules with the “place hotspot rules here” comment?
The problem is that these rules appear at first by overlapping the 2 rules I need at the top.
I think I was able to create a startup script to move to the top again but that is not the solution. I would like to know the root cause.
I created a ticket sent the supout, but I was ignored.

Palliative script with contour solution:

/ip firewall filter print
/ip firewall filter move [/ip firewall filter find comment~"Hotspot - Separa o trafego "] destination=0
/ip hotspot disable [ find ]
/ip hotspot enable [ find ]
