Position numbering in standings does not reflect head-to-head

Hi Sportspress team,

Thank you for your great plugin. Yesterday I noticed the following:

In the league standing, the ordering is correct, but the nummbering is not displayed accordingly. Please see https://www.deltameiden.nl/middag/?target=poule-a-(mo19).

Imho the position should have been 1 2 3 4, based on teams mutual result, and not 1 1 3 3.

Sort order is configured:
Manual (added it myself, but are all empty(-) in this case)
P (points)
DS (Goal difference)
DPV (goals for)
Head-to-Head (set in Configure->teams->Standings>

Is this expected behaviour or did I miss a setting somewhere?

Kind regards,
Marc
