How to set minimum temperature in auto mode?

During this time of the year, the weather fluctuates quite a bit and I use the auto heat/cool mode (state = heat_cool) and set boundaries using Nest itself. However, I want HA to modify by reacting to particular states instead of a fixed time. I found in the automation where I can set the temperature, but I don’t see how to choose the maximum (target_temp_high) or minimum temperature setting (target_temp_low).

This is the view that I have:

While I was tinkering I did see a pop-up dialog that asked me to set the temperature range, but I can’t see to get that back now. I can add this in manually, but wanted to see if I was missing something here at the UI level or if this is some bug.

target_temp_high and target_temp_low are set in the Climate

and the other bit is a in lovelace climate

if I click the Gas Heater I get that popup

entity: climate.gas_heater

I must have bumped something and thought I was in the automation when I wasn’t. When I chose to edit as YAML, added the code manually and then went back to UI mode, I got this:

That’s different from the first screen shot. That seems like a bug, but not sure. Regardless, adding the code manually resolved the problem.
