This looks like an old org bug that has been fixed in newer versions.

I just tried this with

Org mode version 9.1.5 (release_9.1.5-1784-g772949 @ /home/neil/src/org-mode/lisp/)

and I don't see the problem with that version.  What version do you have?

This seems like an unlikely bug because it's very basic to org-mode tables, but if I'm doing something wrong I sure can't figure out what.

I have this table:

| Date                   | Count | Pages |
|------------------------+-------+-------|
| 2019-Aug-03 (Sat, 215) | 2069  |     7 |
|                        |       |       |

but when I hit TAB or C-c C-c to reformat the table it is displayed as in the screenshot

 

Copying the text with M-w is still the same.

| Date                   | Count | Pages |
|------------------------+-------+-------|
| 2019-Aug-03 (Sat, 215) |  2069 |     7 |
|                        |       |       |

I'm immensely puzzled.
