Bugged censorship - Czech language unusable

After trying to write anything in Czech language the text is censored where it definately shouldn't be. This is list of words that I found to be censored in my world.

Úsvit - sunrise
skok - a jump
perfektním - perfect

I tried copying a famous fairytail into a Minecraft book from here https://www.pohadkozem.cz/o-cervene-karkulce/ and this is list of censored words in the fairytail. So many basic Czech words don't work, that Czech language can not be used.

jí - her
začali - began
se - czech pronoun or part of a verb
vydala - went (somewhere)
potůčku - stream of water
se snažil - he tried
chaloupky - cottages
v - in
přičichl - he smelled
vnučky - granddaughter
dočkat - wait for
abych - to
zpátky - back
znovu - again 
mu - him
samou - by it's
