Or how do I remove the hotend temp from the profile so it will use the material temp instead?

Then why even have material settings if they never change what is on the sidebar? That seems like a lot of wasted work on both the programmer and the user if changing materials doesn't change the temp to the preferred setting. This also doesn't sound correct since it will change the print bed temp just not the hot end temp. What am I missing here?

Any suggestions for this or is it a bug?

What happens for me is I have it set to a PETG material I created with the temps I use. It didn't change the temp to what I set so I change the temps manually. When I switch to a PLA material I also created it does ask if I want to keep or discard the changes that I set manually that didn't change last time I switched materials. I click discard and it changes to the PLA settings. Seems like what you describe. Then I immediately change back to the PETG material without making any manual changes and while the build plate temp changes the printer temps don't change and it doesn't ask to keep or discard any changes.

So is this intended behavior or is it a bug that needs to be submitted somewhere? If intended I am curious why.

When I switch to any material the temp stays at 210C or what ever the last temp was.

I see that when changing materials the hotend temps (default printing temp) is not updating. Also I see there is no link icon like the build plate temp if that is an indicator of something.
