Export Shapefile duplicate column names (first 10)
Notice, the current version 5.34.2:
When data is exported as Shapefile and then Imported as Shapefile again columns might disappear.
waterlevel_low_min | waterlevel_low_max | waterlevel_high_min | waterlevel_high_max
will be exported as:
waterlevel | waterlevel | waterlevel | waterlevel
And then imported as:
waterlevel
Other applications might struggle with this as well. Conversion by other applications will be solved like this:
waterlevel | waterlev_1 | waterlev_2 | waterlev_3

One underlying cause is the shapefile field name length limitation of 10 characters.
