Oscilloscope: Settings for Math and XY plot are not saved in the ini file

[andreeaipop]

OS Version: Windows 10 (10.0)
FW Version: v0.25
SW Version: 3d4c582

Description of the bug: When an ini file saved from Scopy is loaded back in the app, it does not have the settings exported for math channels and XY plot.

Steps to reproduce:
Open Oscilloscope, add a Math channel and configure it to 50mV/Div and change its position.
Enable the XY plot and configure it to dots and M1 on X axis and CH1 on Y axis.
Save the ini file.
Reset Scopy and load the previously saved ini file. The Math channel is at the default 1V/ Div and position 0. The XY plot has the default axes and is set to lines.

Also after loading a ini file that was generated when a Math channel was active, the buttons for General Settings and Channel settings at the top of the page become unresponsive.

See below a picture with the configurations I made and saved the ini file:

And after resetting scopy and loading the ini file:
