Created attachment 75540 [details]
This is an example of math formulas which have lost the alignc command and have added excess characters.

Problem description: 
After creating simple math formulas, OO-Math adds undesirable characters.  I also drops formatting functions like alignc, alignr. 

Steps to reproduce:
1. For example: I will type,
tilde n `=` {left ( sum w sub i right ) sup 2} over
{sum w sub i sup 2}

widetilde {n} = {{left (sum {{w} rsub {i}} right )} ^ {2}} over {sum {{w} rsub {i} rsup {2}}}

2. when I type: {alignc n} over {abcdefg}
Then save the document, then reopen the doc. it deletes alignc.
After opening it becomes {n} over {abcdefg} {}
3. ....

Current behavior:

Expected behavior:
Really is a big problem I cannot trust it at all.
              
Operating System: Linux (Other)

Confirmed. It is actually a docx export problem.

The mentioned formula format function totally missing when exporting to docx:

{alignc n} over {x}
{alignl n} over {x}
{alignr n} over {x}

Namely, save the document as odt file doesn't trigger the problem.

Nothing changed. Tested with LibreOffice 4.4.2.0.0+ built at home under Ubuntu 14.10 x86-64.

Changed component to filters and storage, because it is a problem of OOXML export.
