Work is being displayed as 1d 19h

Hello All,
I am trying to orient myself to mrproject for the last two days (my 
final hardle to make myselft a pure linux person). But for some unknown 
reason, the Work columm is being shown as md nh (e.g. 1d 19h). This is 
very inconvient for me. Please tell me how do I correct it. I am using 
0.9.1.

Thanks in advance.
