I18n: already translated label is not added to po template

When I launch gulp task for generating po template, an input label only containing “Query” message is not added to template.pot
If I manually add the message in .po file, it works.

If I replace it by “Query_cust”, a new message is well added in template.

I suppose it is because “Query” is already translated elsewhere, but can I force template generation for all messages (ideally with available translation already filled out)?
