Flatra's In hand figure is simple arithmetic: opening balance + everything collected − everything spent. If the opening balance is wrong, every number after it is wrong. Enter it once, honestly, on day one.
Don't put a flat's unpaid dues into the opening balance — they aren't money you hold. Instead add an adjustment on that flat for the first month you generate (Maintenance → adjustments icon). It appears on the flat's bill as "Previous balance" and the resident sees exactly what it is for.
Check three things: the bank balance was entered as Balance (not Corpus), no expense was added before the opening funds, and no payment was recorded twice. The statement screen shows the running total month by month so you can see where it diverged.

If the society can spend it on monthly expenses, Balance. Only money deliberately reserved for big future works is Corpus.
Usually an expense was recorded before the opening funds were entered, or the whole balance was saved as Corpus. Fix the entry and it corrects itself.
Residents see the association balance summary when expenses are shared; the detailed statement is for the committee.
