Wrong title text color on Android P

[Looki75]

Hello,

I'm using your plugin (precisely: grid sheet) on both of my phones:

• OnePlus 7 Pro with Android Q (stock Oxygen OS)
• OnePlus 3T with Android P (stock Oxygen OS)

I use "black theme" in system settings.
On the grid sheet I setup the background to black color.
On Android Q: all texts (title+labels) appear white as soon as the background color is set to black.
On Android P: same behavior for labels, but not for the title, which is of black color.

If I set manually the labels text to be white (or another color) label texts are as expected, but titles texts remain white on Android Q (which is OK for me) BUT remain black on Android P (and thus preventing any reading).

Please help.
Thanks
