jzchen_2000 - can you clarify a few items about the issue you reported? 

The MD PTE clients you are referencing - are they MD Form 510 filers?  

If so, are they electing to remit tax on resident members' share of income?  Or are they only submitting withholding tax on behalf of nonresident members' share of income?  

Any more detail on the scenario you can provide would be helpful in my investigation of the issue.  

Thanks for your help - hopefully we can get to the bottom of the issue quickly.
