Selected/displayed charger types not consistent when zooming in/out

Charger Icons "flipping" and "vanishing"

Very often, the charger-icons are overlaying each other in a undetermined way - and when zooming in, some of them vanish rather than become “better visible”.

Example:
Here we have apparently 2 Ionity Chargers:

Zooming in…
They turn into EnBW and a smaller ChargePoint-Charger:

May happen on crowdy spots, so let’s zoom in further to get all the chargers available:
No more Trace of the Ionity chargers…

Well, they are there, just not displayed anymore.
If one wants to use them, you have to try to click the icon on the highest zoom level, which is tricky.
