note read out not making sense-bug?

In frequency mode when the cursor is placed on the read out it displays hertz and musical notes. Great…except on my computer the -/+ cents does not make sense. For example it runs from C5+0c to C5+49c and then you would expect it to go to C#5-49c but it does not it goes to C5-49c and on to C5-48c etc. Then it will change when it gets to C#5 as expected. This is true for all notes and I’ve tried it in DP and Twisted Wave with the same result. It feels like a bug but is anyone else experiencing this? Great plug btw!
