Data stored at Parent level, can't even delete it?? BPC 10 NW

Experts,

I am experiencing something weird with BPC 10 NW. We get the ledger data from ECC and when we loaded the data in to BPC, it shows the data at parent level accounts?? Check the following screenshot. We have some data at the base level accounts but you see the wrong total at the parent level.

I tried to delete the data for that entity and for these accounts but it would not delete the data from the parent level. We also fully optimized the cube but See the following screenshot. We dont see anything at the base level but parent level account still has some data.

have you ever experienced this? can you please suggest something here? Thank you very much in advance.

Mandar.
