OO and Libre Office have a langstanding bug 

https://issues.apache.org/ooo/show_bug.cgi?id=7747

The select all function does not work in a  document which starts with a
table there is a workaround but this workaround does not work for odt
files generated by the org converter.

Now I generated by the org converter a document which I attach,
Please look at the following document, which has been generated by a
converter provided by org[.

It contains tables which whose text cannot be selected via select all.
If there is something wrong with the odt, please tell me and I will
report it on the org mailing list.

thanks

| notwithstanding dave's comment, the odt seems either defective or
| incompatible with aoo (which may be aoo's fault as well). more
| specifically, the tables are quite lonely within their sections. they
| have no text before them, nor after. such a document can't be created
| by usual means of aoo, and thus it isn't handled as expected. e.g.,
| you can't type anything after the second table or after the first one
| within its section, because there're no empty paragraphs after the
| tables to take your input. you can't even peform select-all operation
| manually (with a mouse rather than through ctrl+a). it seems that the
| select operation uses contents of the <text:p> elements to set
| boundaries of the selection. so, if there's no such element, then
| select-all doesn't work properly.
| 
| to fix this, i inserted the following two paragraphs into content.xml of your file:
| 
| <text:p text:style-name="OrgTableContentsLeft">some text after the first table</text:p>
| <text:p text:style-name="OrgTableContentsLeft">some text after the second table</text:p>
| 
| they follow the closing tags (</table:table>) of tables. there
| appeared to be no way to do it through gui.
| 
| after that select-all worked almost smoothly: it selected the cell on
| the first press, the table on the second one and everything on the
| third one. what was wrong is that it always started with the cell,
| even when the caret was outside table.
| 
| however, inserting a paragraph before each table fixed this. it didn't
| require editing content.xml. the final version of the file is
| attached, and i hope it won't be attenuated by antispam.
| 
| i can't say on which program's account this bug is. consulting odf
| specification may help answer this question

I attach both files:
