How should I report an incorrect translation in the user interface?

[jazei-AR]

Help me... Report Wrong translations in sj U.I. where in this forum?
sending the report via https://www.slimjet.com/en/onlinefb.htm?
sending via https://www.slimjet.com/es/onlinefb.htm? notice .../ES/.... in English? in Spanish? I think there is no one reading in Spanish here
for example these reports
1) In the title of the popup window with the weather forecast, a space is required between the comma after the name of the City and the name of the Country.
2)In this window (https://www.slimjet.com/es/onlinefb.htm) below there is a button said "Perdí" but it is a wrong traslation.... It should say "Cancelar"

1) That's just sloppiness. It would be the same in English.

2) I'm literate in Spanish, and having looked at that page (in Spanish) I agree.
