Maybe n00b but..
When you want to place a buy order, just click on the price you want on the sell table, even if not the first one.
It will sum up to the available minimum value. This is ok to wipe those 0,0000x
Same if you sell.

example:

0.0902   0.04699048   0.004238541296
0.0903   0.04620559   0.004172364777
0.0904   0.05059926   0.004574173104
0.09046   2.4786566   0.224219276036

I put cursor on buy form, then double click the 4th so I have a sum of the previous 3
