Einige was a new word and displayed itself as the verb to unite, not "some"

What is the difference between "Einige Fragen" and "Manche Fragen"?

I knew the word "Einige" and got the correct answer, The definition given makes no sense, does it?

some is not given in the list of meanings

Seems to be wrong to me.

"some" should be at the top of the suggested translation.

Is "some issues" wrong?

how is 'any questions' wrong? it's used the same way as einige fragen, for example at the end of a presentation. "any questions?"/"einige fragen?"
