Why my text always lose formatting?

I have a subtitles for video in .txt, first line targ lang next line native lang , once I import it to lingq its MERGE ALL lines and create A MESS .
and if there is any language besides the target one , lingq not able to find the ending of sentences even they have right punctuation
for example
Похоже, что на них донесли.
快走 上车呀 快点
Быстро в машину!

Lingq cant divide text by sentences and shows me whole 1000 words in one page .
even I press show me 1 sentence it doesn’t …

I am mainly study by reading bilingual texts but seems its impossible to use lingq this way…
is there any solution?
