Issue with Rounding Number Token in Renaming Action (Hazel

Hello, I'm encountering an issue with rounding a number in the renaming action using Hazel 6.0.4. Here's what I've tried so far:
Selecting 0 from the dropdown, which should round the number to a whole number, doesn't seem to work.

I used Edit Number Format and entered the custom format specifier %.0f, which I expected would round the number to zero decimal places, but it has no effect. As a workaround, I attempted using the Adjust Number… option (e.g., adding 0.5) to force rounding before formatting, but that also hasn't produced the expected results. Could you please advise if there's a bug in the current version or if I'm missing a configuration step? Any guidance or updated documentation on how to correctly round numbers in the renaming action in Hazel 6.0.4 would be greatly appreciated.

Thank you!

You can't enter format strings like %.0f. As of now, there is no way to format decimal places. If anything, numbers will be truncated (floor) instead of rounded.
