Problem With Simple Conductive Heat Transfer Simulation

Hello, COMSOL noob here attempting a senior design project for school.
I am attempting to model a very simple block of Mo (at room temp) placed onto a heated stage (at 250degC). However, my solution becomes a uniform temperature of 250degC immediately.
To combat consistent intialization I have a ramp starting at 0 for the temperature boundary (as suggested here). This just yields the entire model heating uniformly along the ramp.
Any pointers would be greatly appreciated!
I've attached my program. I have tried different types of boundaries and added/removed geometries but to no avail. I have also tried changing the heat convection parameters but they have no effect. I have also tried a swept mesh but it yields a gradient in the wrong axis. Excuse any dumb mistakes, my team and I are learning this program on the fly.
Thank you so much in advance!

See the attached model with corrected mesh.

Thank you so much! This helps me understand a lot better.
