VLANs not going across fiber connection When I tag them, it becomes untagged even though others are tagged. Also tried a Trunk and that did not work

Afraid, the crystal ball is not available here.
Provide much more information what you had tried to configure, being from screenshots or from CLI example.
Start with the firmware version, the SFP module versions, the fiber technology, wavelength, ...

I have a single-mode fiber between two buildings connected over the SFP ports. M4300-24x24 port 22 and M4300-52G port 51
I have setup VLANs, 220, 230, 240, 260, 270 on both switches. I tag port 51 with the VLANs no issue, when I tag port 22 with the VLANs it switches it to untagged.
In short, just trying to pass tagged traffic across the fiber.
