i18n missing lines

Is is normal that the i18n file is missing quite a few lines? For instance, you can find there “open solution” but not “new solution”… (using version 2.2.4)

Hmm, seems that we can only translate msgs used in the client version, not the dev ones. So, I live with a mixed version since I have not found how to remove the custom version; even with the i18n server not specified and restarting the whle thing, the custom msgs are still present, arggg…
