One day whose visits are not shown in evolution reports

[anonymous-matomo-user]

On my site something weird happened in piwik: the visits of July 5th are presented in the "visit by server time" graphics (but only until 8pm), but the daily total shown in the "evolution over the last days" report is 0.

All the other reports show values different from 0 for that day.

I'm going to attach screenshots.

Nothing significant has happened on the server that day, nor the piwik code has been touched on the web site.

The day after, July 6th, everything is ok.

I don't know whether this bug is reproducible, and I'm reporting it in case any user has seen anything similar.

Is there any way to recalculate the report for that day?
