Unable to delete quick links in input schedule

Hi,

We are on BPC 10.0. We have created a input schedule for balance and added quick links where necessary.

But automatically system updated quick links to other members which we don't want. I tried to delete the link (Quick links -->delete member link) and after saving to server, the links remains on the cells.

Could you please let me know if we are missing something.

Thanks,

Suman
