Nested Subform field with min attribute saves with error

[niosme]

Steps to reproduce the issue

https://www.awesomescreenshot.com/video/28634289?key=0cd544c850693dfbd16aaaccae2adae0

Subform into a subform doesnt save correctly the data. Also showon doesnt work right.

I attached a module that i used in the video and you can recreate the problem by going into the special hours tab and trying to add something there and save it. In the first basic tab everything works fine as expected.

When a subform into a subform save doesnt work as expected.

Expected result

Show on to work and save the data as we did them.

Actual result

The data and structure changes and adds more than it should

System information (as much as possible)

Joomla 5.1.0

It is because min attribute in the nested subfrom seems buggy. Without min="1" it works fine.
About radio switch, there already an issue #40160

Removing min attribute also fixed the show on functionallity.

If i find something it could help more i ll attach it here!
