Ascents not correctly grouped per date+area

[senn]

ISSUE:

When showing ascents, some ascents are not grouped together per date and area. Demonstrated on this screenshot of a logbook:

The ascents are made on the same day, in the same crag and area, yet one of them stands alone.

EXPECTED:

Ascents on the same day in the same crag and area are grouped together.

What I can see via web UI:

• log dates:
  • 2021-03-09 Orangina
  • 2021-03-09 Toast
  • 2021-03-09 L'Orange Sanguine
  • ...
  • 2021-09-19 L'Orange Écrasée (en traversée)
• ascent dates all 2018-06-30

So I can't see what the issue may be. Timezone issue, wrong sorting, wrong grouping...

Shame that the source code for the website isn’t available or would take a look myself…
