Internationalization stopped working for CAP CDS: invalid file name i18n.properties.properties

Hello,

some time ago I defined a set of labels for each of my entities properties through the usage of an annotation referencing an i18n file. It worked for a while until I started to experience an error when running the application similar to the following:

Corrupt .properties file: /home/vcap/app/_i18n/i18n.properties.properties

So I renamed my i18n file removing the suffix ".properties" thinking it was automatically appended in the latest releases. I did not get the error anymore but I see that the internationalization has no effect since then. Weird thing, according to the documentation the suffix should not be removed. We also had to get back to previous versions of cds and we still keep getting this error. Any idea on how to solve it?
