The bug
The advancement for killing a mob within the range of a sculk catalyst, entitled "It spreads", does not require that sculk actually spread as a result of this killing. As such, the advancement's name is somewhat misleading.
How to reproduce
Place a sculk catalyst in a region surrounded for a reasonable distance in blocks neither sculk nor sculk veins can spread to, such as mud (MC-249208)
Kill a mob in range of the sculk catalyst and on the mud blocks or whatever else was used
Obtain the "It spreads" advancement without spreading anything
Expected results
Either the advancement would require sculk to spread before being granted, or it would be titled something different to make it less misleading.

Also can confirm. It occurs some problems on crowdin translating, please fix it! (And yes, I am a proofreader)
I can confirm this. Just to elaborate and make crystal clear, the requirement for obtaining this advancement is to "Kill a mob near a sculk catalyst", and the title of the advancement itself is "It spreads", so being granted this whilst no sculk spreads or forms it quite strange and a bit misleading.
