[O] clocktables include "\emsp" - how to get rid of that?

[Rainer Stengele]

Hi,

I am getting "\emsp" in my clocktable reports.
I use

#+BEGIN: clocktable :maxlevel 4 :fileskip0 t :tcolumns 0 :level nil :scope 
agenda-with-archives :timestamp nil :block 2015-03 :step day :link t  
:stepskip0 t
#+END:

to create these clocktable

|                       | \emsp [[..][Project Managament: Weekly meetings

|                       | \emsp\emsp [[..][TODO *00 - Project Managament -...]] 
           |   2:45 |

Anybody has an idea where this comes from and how to get rid of it?

Thank you.
