Inadequate light & humidity can cause this. Indoors BOP need to be misted frequently - particularly in winter. And how much light? Near a window?
Since I brought mine in (6 footer) ~ Oct 12, many leaves are shredding and I mist mine.
Indoors they have a tendency to do this - but yours is quite extreme.
The ends of leaves start to curl and roll back (upwards) and then they rip.
Beyond the above, not much you can do about it and nothing can be done to "fix" the ripped leaves. (Sorta like banana leaves out doors ripped to shreds.)
Good luck.
