Extra scratch folders for 6.1

I’ve noticed that for v6.1 the scratch directory winds up with two directories being generated.

Here’s the Linux command line

qchem -gpu -nt 60 md2_356_FLI1_qc_nochgs_ROK_DIIS.inp md2_356_FLI1_qc_nochgs_ROK_DIIS.out md2_356_FLI1_qc_nochgs_ROK_DIIS

For example:

md2_356_FLI1_qc_nochgs_ROK_DIIS
md2_356_FLI1_qc_nochgs_ROK_DIIS.0

Never saw this happening with previous versions of QChem. How do I stop this?
