Animation blueprint not connected properly?

So this is my first project and I’ve started a new character using a new skeleton. I basically duplicated the ABP and changed the skeleton to my new one and fixed any of the warnings that popped up. At first everything worked fine with the standard animations but as soon as i started making the upper body anims and applied them, they didn’t do anything. Which is when i noticed that the connections to my new one are missing the yellow line in the connections. I assume this is where my issue is coming from but i’m not sure what the issue is. Does anyone know what the problem could be?

The images below show the new one first and the old one second. The old one is using the ue5 manny skeleton and the new one is my new skeleton
