Translating problem

Hi there,

I am using the free version of this plugin and I am really happy with the functionality it offers!
However I have came up with a problem translating few strings. The calendar name on top is translated like: Dogodki v marec 2019, when it should be just “Dogodki marec 2019” (without v, as it is not correct) and also when you have a button “Find dogodki”, I need to translate that “Find” word or even better just make it write “i??i” as a full string.

To translate all the other things I managed to do it with .po file, but this two seem to be fixed somewhere else.

Any ideas where I could translate them?
