Nonsense error when increasing LightSource angle?

Question

My project has a Light Source and a Sky Sphere Blueprint.

The rotation on the y axis (Light Source) defines the position of the sun (Sky Sphere Blueprint).

Character Blueprint (increases by 10 degrees on the y-axis rotation of Light Source, the updates the position of the sun):

When you click the button (Angulo, circled in pink), the angle increases by 10 and works to a certain moment:

Image with angle increased by 10:

When it reaches 100 degrees, it starts to go wrong. Each time I click the button it goes from 90 to 100 and vice versa in an infinite loop:

I've already tried to turn it around, subtracting instead of adding, but at one point it also gives error (in the case with 110 degrees).

Sounds like you might be experiencing an issue of angle wrap-around when using Euler angles, similar to this issue a user encountered using these angles in Unity. — DMGregory, Jul 15 '19 at 02:10
@DMGregory I saw your answer and it opened my mind, helping me find a solution. Soon I will post how I solved my specific problem. — Boneco Sinforoso, Jul 15 '19 at 22:41

Based on @DMGregory comment and also on his answer given in another question.

Question link where he gave the answer that helped me:

Why rotating an object only on its local X axis result in sudden 180 degrees changes in Y and Z axis rotation values

I stopped using the value coming from the rotation of Light Source. I have stored the desired value in a variable and set it directly in the rotation of the Light Source.

First I did a test using a switch and it worked:

To optimize this, I used a structure and a data table:
