Due diligence

• I checked for similar issues and couldn't find any.
• My WebUI and Unprompted are both up-to-date.
• I disabled my other extensions but the problem persists.

Describe the bug

Hi,
After reading this AUTOMATIC1111/stable-diffusion-webui#11966 I install unprompted and start the tutorial. It works ! Now I'm trying to use the batch_seeds_custom_step_size as mentionned in the reply you give but nothing happen. I firstly use
[file common/examples/batch_seeds_custom_step_size step="{random _min=40 _max=42}"]
And also try
[call common/examples/batch_seeds_custom_step_size step="{random _min=40 _max=42}"]
