RFE for EVL then LUD's for two days

[gcby2099]

I joined new job using EAD, didn't invoke AC21, my 140 was approved and I filed 485 in July2007.

There was a RFE for geographical discrepancy explanation and EVL from 140 filed employer or EVL from new employer if changed jobs on 04/29/2009.
(Changed address using AR11 after filing 485)

RFE on 485 on 04/29/2009
LUD on 140 on 05/01/2009
USCIS received EVL from new employer with AC21 - on 05/11/2009
LUD on 485 on 05/13/2009
LUD on 485 on 05/14/2009

Don't know whether they are soft LUD or Hard LUD.

Couple of questions, Is LUD on 140 normal when there is a RFE on 485?
Continuous LUD's on 485 normal?

can some one answer ...

thanks in advance...
