Alpaca Cash Disappeared in Paper account

I had initiated with 100,000 on my paper account.
Portfolio value is around 47,000 ( This was $97,000 yesterday and there is no any noticeable loss to have this big dive.

Equity= $30,530.66
Buying Power is $9700 (which was $0.00 some minutes ago.)

Why is the cash disappearing is the concern and the values under Equity, Buying, Power, and Portfolio does not align well and is incorrect by far.

Please help resolve this issue.
