Hello guys. Still can't fix this problem, becouse can't find COM_EASYSOCIAL_STREAM_APP_FILTER_K2 in Language settings, and can't find it in file (.../language/ru-RU/ru-RU.com_easysocial.ini)
Please help.
It seems that those strings, still not translated by our translator as those strings are still new. I have made language override for it and it should shown correctly now.
