Tint in Character Style bug

[Robert at ID-Tasker]

Not sure if anyone reported / noticed it before:

As you can see - there is NO color defined - 31, 32, 33 - BUT there is still 70% TINT applied...

First "31", the on the left - is 100% - on the right, in the applied CharStyle - it's 70%.

But if I turn OFF color - 1st screenshot - tint is still affecting text - but can't be changed without applying some color first... 

Yes, it's handy if someone needs to just change tint of the color applied in the ParaStyle - but then it should be editable?

Is there a GREP or nested/line style set in the Paragraph Style? Looks like something that kicks in on first word or after a colon.

CharStyle is applied to the 2nd 31 and following 32 and 33. 

It's the file from:

I was playing with it to align those numbers - and noticed, that even if I'll turn off color - tint percentage is still applied - which is OK - but isn't directly editable.

I see what you mean. Tint % should be adjustable even if no colour is selected. This is in 20.2. I can select a stroke weight without selecing a colour, but still no tint %.

Exactly.

How about something like this - should I start a new thread?

Object is selected - NO COLOR to stroke applied - but I CAN change Stroke's tint...

Which results in [Black] being automatically applied: 

But what's worse - text goes into an overset - even when there is enough space for the Page Number marker??

AND it doesn't get fixed/updated on regular pages - same contents and size of both TFs:

The only way to fix it is to change the width of the TextFrame from "105.853 mm" by "0.3306 mm".
