When I select the current value of 179 and enter the value of 161 value for a letter, I get a result as in the picture, with the old value preserved instead of the new value. I have to repeat the same process several times to enter the new value. Is this a bug caused by the program? Sometimes I run into this problem that I mentioned.
Yes, this is a bug. It will be fixed with the next upcoming release.
The update we released earlier today contains a fix for this issue.
