Developing help

Here is the results of my last 2 rolls of film I developed. The 120 has 3 photos that show up, one of which has an odd line through it. I assume the others not showing up are camera issues? Or could it be a development issue? The 127 is almost totally black. It has clear lines in between the images so I know it wasn’t exposed to light out of the camera. Reckon that was just a camera issue or could that be a development issue?

Camera issue, development looks good.

Looks like a shutter that remained open for an extremely long time. Maybe even permanently.

The other roll is excessively underexposed.

Inspect both cameras and in particular verify the working of the shutter on the 127.
