Goods movement issues in WM

i have one in production,

i posted 35.200kg stock through mb1c with 561 movement type,(now available in 998 storage type)

unfortunately i transfered 30kg stock dircetly from 998 to 150 storage type(production).

so i this case TO has confirmed automatically,

my issues are

1. system created 5 TOs and confirmed all TOs by moving the goods from 150 S.type to 150S.Type(both Source and Destnation are same) so why it is?

2. meanwhile its created 24.800- kg Negitive stock in 998 storage type, can any one guide me how can i ?

3. if we posted in again MB1C with 561 for the 24.800- n negitive stock what will happen?(but this is real besiness transaction that's why)

can any one guide for the above issues.

Regards,
