Can't update sunrise and senset times in KDE Plasma 5.15.5

[LedBass]

AutomaThemely isn't updating the sunset nd sunrise times when using the UI in KDE 5.15.5 (KDE Neon) as shown in the image

Steps to reproduce it:

1. install AutomaThemely using the file provided here
2. Set the Look and Fell for Plasma and GTK in both light and dark tabs
3. Set it to get Automatic location
4. Press "Save" (the application closes)
5. Update the Time Offset (in minutes) field (in this case +60 for sunrise and -for sunset)
6. Press "Save" again (the application closes)

Expected behavior: AutomaThemely changes the theme of Look and Feel and GTK properly as configured
Found behavior: It still uses the old sunset and sunrise times

Below I've attached a screenshot with my case, the sunrise and sunset is still as it was in summer saving time even though I've configured it to update and use one hour earlier for sunset and one hour later for sunrise:

The first time it ran, it configured it self to change themes at 18:27 (6:27 PM) and stick with it no matter what I do to update it's sunset and sunrise times
