I can see the strings for the languages I just checked. Can you let me know the language you are using in your Survey? Maybe it is not yet translated

I am using Portuguese (Portugal).

Maybe it is not yet translated

I am the Supervisor of the Portuguese (Portugal) and those strings don't appear in GlotPress to be translated.

In French is the same:

Groupe de questions : (ID:1233)
Code : Q00 : (Question optionnelle)
Question : Indique as atividades que você desenvolve na sua Unidade e o tempo dedicado a elas em termos percentuais:
Aide : Este é um texto de ajuda da pergunta.
Type : Multiple Numerical Input (Type: K)
Obligatoire : Non
Condition : 1
Filtre conditionnel du groupe : 1
Maximum sum value: 100
Minimum value: 0
Maximum value: 100
Use slider layout: 1

-- João

I mean the strings with the colon(:)

For example the string "Use slider layout" is already translated but the string "Use slider layout:" does not appear in GlotPress to be translated

This happens for all languages. The translation does not need to have a colon to be picked up I guess. I will pick it up from here. Thank you for reporting.

The question attribute names were not being translated in the summary view.
