Merge to HDR quantization artifacts

I have a strange case of artifacts when using Merge to HDR Pro script in Photoshop CC.
I am using 32-bit mode for HDR, but the problem exist in 8 or 16-bit, too.
There is severe quantization of the image when 3 exposures are used, as seen on the picture (look at the trees, etc.).
The sample files with the exposures are attached.
Could anyone reproduce this?
Is it a bug in the script / can this problem be fixed?

lambiloon, your answer is too ambiguous.
I think, you didn't pay attention that I'm using Photoshop and Automation>Merge to HDR script in 32-bit mode (without tone mapping).

davescm, thanks for your answer!
No, i haven't yet tried version 21. Interesting coincidence!
I see that there is some bug report of problems with HDR, though not much info.
Probably, Merge to HDR is buggy and wasn't meant to be used seriously.

It was a bug that came up in CC2019 and is fixed in today's release

Dave,
Have you tried just my sample photos in 2019 or 2020?
If it's not too much to ask.
Is it a problem that depends on combination of hardware and software or can it be reproduced on other machines?

PS 2020 is no better in this regard.
Here is a "nice" posterization effect of Merge to HDR.
