New (2024) Player's Handbook Bugs and New videos

Indeed, those fields have changed. Have you tried to swith to Legacy mode and then back to 2024?

It seems there's no saving throw field in 2024, yet I could input them in the skill field as per attached image, since the save modifier cannot be edited with the creature proficiency bonus.

As you say there's no Saving throw field in the 2024 NPCs. We may have to wait until the Monster Manual comes out to find out why that is; but at the moment we have to assume that creatures won't get a bonus to saving throws beyond that which they get from an ability score modifier.

You will need to work out what their skill bonus is if they have proficiency in a skill - just like in your image. Having said that the first creature I looked at in the new PHB (Black Bear) has noted its Perception skill at a +5 which doesn't add up with it's ability modifier + it's proficiency. So it would seem that the Black Bear actually has double proficiency in that skill.

A creatures proficiency modifier (probably) depends on its CR - as it did in the 2014 version of 5e; this is a calculated field and therefore not editable.
