Reference is poorly adapted when translating "Tradícia_(zvyky)" for from Slovak (sk) to Czech (cs). The result shows that the reference has plain text content extracted from a warning message of the filled template, in addition to the filled template:

Original in Slovak (version used):
...medzigeneračného prenosu.<ref>{{Harvbz|Shils|Rok=1983, ©1981|St=15-16}}</ref>
Translation to Czech (view version translated):
...mezigeneračního přenosu.<ref>{{Harvnb|Shils}}Je zde použita šablona <code>{{[[Šablona:Harvnb|Harvnb]]<nowiki>}}</nowiki></code> označená jako k „pouze dočasnému použití“. [[Kategorie:Údržba:Články s dočasně použitou šablonou]]</ref>
Two aspects to consider:
- Warning text leaking as content. 'Je zde použita šablona Harvnb označená jako k „pouze dočasnému použití“' means 'Harvnb template is marked as "temporary use only"', which is a warning shown on the Czech version of the Harvnb template that leaks as content. Avoiding this is the main scope of the task.
- Using the preferred template. The equivalent of sk:Harvbz is cs:Harvnb according to Wikidata. In this particular case, the Harvnb templated is discouraged in Czech Wikipedia (which is communicated in a template at the top of the template description page) but overriding the Wikidata equivalent template for some other community preference is a separate issue.
The scope of the current task is to adapt the template to the corresponding one according to Wikidata without anything leaking as content outside the template. Selecting a different template is not in the scope of the current task.
We want to focus our efforts to verify this for version 2 of Content Translation
