  • Are you sure this is the same layer? Which data type does it have? Did you run any operations on it?

    It simply looks as if you don't have any attributes. If you had them before, could it be you deleted them?

As @JGH pointed out, part of the problem may be that your DBF file is corrupted, and it is.

I opened the dbf in a hex editor and some bytes needed to read it are missing. The bytes 8(08) through 10(0B) were zeroed, these bytes tell you how big is the file header and how big are the records in bytes. Your first byte value is a zero too, which is a valid value from the spec (as far as I can tell) but doesn't seem to open unless it is a 0x03 value, similar to other shapefiles.

What you had:

Incorrect header

What it should be:

Correct Values

I corrected the values and now your shapefile works in QGIS, and the values remain when in edit mode.

Here is a archive with a working shapefile, hopefully 10 minutes of my work saved you having to recreate 2055 records. Enjoy.
