WRONG! I just tried setting it to lithium AGAIN and the equalization voltage adjustment is not greyed out in my version of the app. Automatic equalization IS greyed out. Move on to something that is helpful.Yes, even if LiFePO₄ is first selected but then you tweak a voltage, for example, it does show "User Defined". But I don't think that LiFePO₄ has been selected because when you do it looks a lot different. For example, the "Equalization voltage" is grayed out and shows "Disabled". The OP's screenshot shows that value as still active. There are a few other changes that I see in my SCC battery settings compared to the OP's screenshot.
"if I selected the LiFePO4 setting in Victron Connect, but then tweaked the settings, it then changed the Battery preset value to "User Defined"
^^^THIS RIGHT HERE^^^
