Hello,
1) http://prntscr.com/k9vhb7 Translation files should be placed in wp-content/languages/themes/with name legenda-he_IL.po and legenda-he_IL.mo
2) I don’t see translation for fields that you mentioned http://prntscr.com/k9vktp Please translate them and then check frontend again. I have translated one of the missing strings http://prntscr.com/k9vqf2 and it works http://prntscr.com/k9vq0p
Regards
