Custom fields replaced by generic fields #3473

(I can´t print the MAP URL, it´s a private map)

I have 5 Layers with different custom fields on each layer.

Bug appears only when creating a new Pin.
Last week everything was fine, today I saw the bug first time

Creating a NEW Pin:

• the dialog on the right shows only generic fields (starting with osm_type, osm_id...)
• no custom fields shown at all

Already created Pins:

• when clicking on pin gereated in the past everything is fine: my custom fields with my stored info is there

Table of the Layer:
All custom fields and my stored info is there
