Form 8889 monthly checkboxes are not handled right by step-by-step

I had HDHP in 2024 for the whole year and for 2025 I only had it for January. Then I went on Medicare for February onwards. When I answer the step by step, I indicated this.

On form 8889 it shows the year 2025 correctly in Part I, section 2.A.

For Part III, Line 18, section B, it checks January as "None" and the rest of 2024 as Self-Only. I fixed this and then when I go back to step-by-step and answer the questions again, it reverts January 2024 to "none". I change that to Self Plan in Step-by-Step. Now when I go to the forms, Line 18, Section B has January as None and the rest as Self-Only.

It seems  to be confusing 2024(HDHP all year) with 2025 (HDHP only in January). It seems to not reflect the value selected for January in Step-by-step onto the 8889 form.

There is currently an issue wherein TurboTax changes the January 2024 amount from Self to None and None to Self. The workaround is to counterintuitively set January to None when you want it to be Self.

This appears to work for both the Online and Desktop products, although in the Desktop products, as you know, you can use Forms mode to manually change January to Self as needed.
