When transferring template content across languages, Content translation can face two different issues:
- Missing template (T192271): not finding the corresponding template.
- Incomplete template (T209473): finding the template but being unable to map the parameters to copy the information over.
These are different issues with different messages. However, I've found cases where an incomplete template adaptation is reported as missing. For example, translating Pont vell de Vilaller from Catalan to English, the infobox is added as "Infobox building" to the translation with their parameters empty (incomplete template case), but the warning shown indicates it is missing instead. This quick link allows testing with a minimal example.
