Liverpool and the jinx of "W" clubs in qaurter-finals

No doubt liverpool fc have been in good form and are a syronger side than they have been for the past 5 years.
Still it seem the club can't seem to break an FA cup jinx that has plagued them for three seasons "W club quarter-final jinx".

Two years ago loverpool were knocked out of FA cup by wolvehampton in the quarter final.

A year ago also 2017 liverpool also were again in the quarter-finals in a match against westham and they lost again........

Now this year, they went against a relagation threatened Westbrom and were the favorites and still lost 3-4, still in the quarter-final.

It has never been about their form because they always play better and dominate the game, which is why am asking are they not jinxed?

If so can they break it next year?
