This word doesn't exist in the dictionary?

On bunpro there is the word 滑らす. That takes the ずらす reading instead of すべらす. The issue is that for ずらす the 滑 kanji doesn’t have a reading for ず it uses すべ.
Bunpro - 滑らす (日本語能力試験 N3) | Bunpro
Jisho - 滑らす - Jisho.org
Am I missing something? Why did they choose this kanji?

Might be a mistake.

Both Bunpro and Jisho (and afaik everyone else) import JMDict dictionary.
The kanji was removed from JMDict entry for ずらす back in 2022.

I have a feeling that similar issues had already been mentioned on these forums before.

Edit:
I believe example sentences in this entry are for ずらす, not for すべらす.

Thanks for the explanation.

Yes that’s the point I was trying to make.
