When I generate a tree, I get some strange empty nodes (more details here).
Any suggestions why this might be the case?
The relevant part of the template looks like this (but in another language):
!style="vertical-align:top; text-align:right"| Parents: |{{#if: {{{parent1|}}} | {{#genealogy:parent | {{{parent1}}} }} }}<!-- -->{{#if: {{{parent2|}}} | <br />{{#genealogy:parent | {{{parent2}}} }} }}<!-- -->{{#if: {{{parent3|}}} | <br />{{#genealogy:parent | {{{parent3}}} }} }}
