for wild boar there is only one labeltype ?

[SanderDevisscher]

Yes, "wild zwijn" there are no labeltypes "overloper", "zeug" of "keiler"

[jimcasaer]

they do not exist ;-)

[SanderDevisscher]

This issue only occurs when you first open the graph for Ree and then switch to Wild zwijn. It is also visable by the labeltypes of Ree being maintained.

Also "labeltype" filter is labeled "jachtmethode".
