Bug? Error B4XSeekBar vertical

I wrote a test program where I use two B4XSeekBars, vertical and horizontal.
If I set, for example, "minimum" 0, and "maximum" 15 in the designer everything works fine. But if I set the "minimum" to 5 and the "maximum" to 15, the horizontal B4XSeekBar works fine, and with the vertical one I get this problem:
Perhaps I am doing something wrong or am I misunderstanding how the B4XSeekBar works? How can this error be corrected?

There is an error in the B4XSeekBar library.
In the Update routine, this line
Dim s1 As Int = Radius2 + (MaxValue - mValue - MinValue) / (MaxValue - MinValue) * size
must be
Dim s1 As Int = Radius2 + (MaxValue - mValue) / (MaxValue - MinValue) * size

Erel needs to amdend this in the XUI Views library.

Fixed in v2.54.
