Y-Axis Not Grouping?

Hi there, I am working on creating a block schedule chart, you can see the table at the top left and what my chart looks like right now. The y-axis represents a different room. I want the block schedule to overlay rooms so that there are multiple blocks in the same row. For example, TUA TOPS OR INTRAOP 2 would have the 4 blocks displayed on the same row.

My problem is that I cannot seem to get them to group together. You can see that in the table I have identified duplicates to ensure that the naming conventions are the same. I have also formatted column C as text. I have also assigned the Axis Type to be "Text axis" as you can see on the right of the screen.

Any suggestions? I think ChatGPT is sick of trying to help me at this point lol.
