certain account lines in report not updating

Hi,

We have created a few reports to give us information on our accounts and the opportunities within.

I have a stacked bar chart which seems to be updating fine, but there are also two sheet-report, which doesn't seem to be updating a few of the accounts (clients) - e.g. for one account the sheet-report isn't updating/displaying all the new opportunities, and only updating some opportunities. infact it still has one opportunity which was already deleted.

i've use the crm analytics>data sync function 3-4 times yesterday, made no difference, and waited over night to see if auto update will help. but nothing this morning.

is there anything i can do to do a hard refresh to ensure everything updates?

Thanks!
