^ and if you can't provide a video was your TPS low (MC-133187)?
Hello Matthew, I'm afraid this is an ongoing problem, also see MC-172880 and MC-133187.
There've been many occurrences of this or similar slimeblock-piston-ghost block issues in the past years, and whilst I found them useful and great for some contraptions, I can see how they can be annoying in other contraptions.
Unfortunately, this is an issue that has to be fixed codewise.
The only thing you can try is to change your timings, as those ghost blocks majorly seem to happen with a piston receiving a 1-tick-pulse, and it also happens on laggy computers, and as I don't know your computer nor contraption, I can't tell you exactly what's happening in your case.
If the ghost blocks are not happening due to a laggy computer, but reliably, please attach a worldsave with your contraption here, even in case a moderator will resolve this bugpost here as duplicate of another one, please still do, I'll be taking care of it privately.
Sorry I can't help you any better here, but you're not alone!
Have a good weekend,
Meri
Cannot confirm.
Happens for me in every singleplayer world.
Can confirm, but only while the game is running slower than 20 tps.

I got a similiar problem on my test world, where an elevator mechanism is creating alot new pistons when it runs.
Confirmed in 1.21.3
