[Plugin: WPeMatico] cron problems with minutes

1st, ty for excelente plugin

i have a problem with cron set in Campaigns… when i set 5 min, or other time in minutes combobox, the next update time is always the next hour plus 5 minutes (or other minutes set).

Exemple :
now = 13:34
i set only the 5 min combobox
save/publish
the next run showed is 14:05

please, verify.

thanx
