Different Stock shows in MBLB and MM03.

I have found a problem in my system,

I have the stock quantity and value for vendor for the material WFLM.

I can see the stock in MBLB.

Here you can see, system shows the stock quantity 489.625 and value 4,896.25.

But I can see the different stock and value in MM03,

Here you can see the total stock and value shows as 287.425 and 2874.25.

How can it be ? How can MM03 shows the lower stock from MBLB ?

I haven't any stock in MB52 (Godown).
