Numeric Fields in the Tone Curve not showing three digits

In LRClassic 15.6 the numeric fields in Develop>Tone Curve are not always showing three digits as they should when the White point is selected. Only seeing two digits is confusing.

 

 

As shown where the white point is select and the Input should read 221 and the Output should be 255.

    Do you see this in other numeric inputs, such as the Amount for Denoise not showing 100, but shows 10?

    No, denoise, sharpening and all other numeric fields are showing 3 digits.

    This has been seen before and is caused by a change in Mac UI elements, specifically the edit box being too small to fit/display the three digits on the Mac.

     

    It was supposed to have been fixed in LrC 15.6, so it is odd that you are still seeing it.

    Yeah I’ve got the panel as wide as it will go - there is plenty of room for 3 digits. I’ve never seen this before and am not sure why I’m being it now…

    Is this happening on a Mac?

    Yes, MacOS 27 and LRClassic 15.6...

    Thanks for the generic response, but your “I am seeing some similar on my end” feels disingenuous and insulting. I have included a screen grab above and therefore a screen recording would only be redundant. I will not be providing these other things unless you can respond more directly and specifically.
