Matomo Graph Refresh

Hello,

We have been trying to delete data in our Matomo for the period in which only test data was being tracked.
We have used ./console core:delete-logs-data, and ./console cache:clear, which seem to remove data (or at least execute successfully), however graphs in Matomo still include the test data on them.

Is there something that must be done to force the graphs to be refreshed?

Many thanks,

Joe

Sorry to bump - is there somewhere else I should post this question?
