Missing or invalid selection for tag tagname in containername.
A tag has been included but it has an invalid value specified for the tag, or there is no value specified.
For example, for a config.txt file:
category-class "AC" category-era "1990s;2000s" category-region description "Model: DB 101 DB"
The error message was:
- VE22: Missing or invalid selection for tag 'category-region' in 'traincar'.
The category-region tag has been included, but no value has been specified for the tag.
If the tag is not required it can be removed, or a valid value can be provided for the tag.
