Yup. There are loads of errors. They're also showing Telugu letters instead of Kannada and Urdu instead of Pashto. Another error I noticed was that the letter (ழ்) in Tamil is shown as [ḻ] like"rag" -- I don't know what rag is doing here, ழ் is the retroflex approximant typically transliterated as zha.

I looked at the Kannada page in some more detail. Good news is that the phrases are in fact in Kannada (unlike the alphabet). But even here some of the translations are slightly off. The one for "he visits many countries" uses "urugalu" (places/towns) instead of "deshagalu" (countries).

I don't get the impression that this is a reliable site.

yup. the order of alphabet is very important for learning telugu (indian languages) and looks like they are sorted in some random order. if you visit the adjective grammar rules and click pronunciation, it pronounces the next rule. that's a big bug especially for new language learners who might not have a clue.
