Quantus: extraction to DSPF fails if "Delete X prefix" option is used

Hi! My extractions to DSPF are failing with the newest Quantus release (21.2.0-p060). Apparently, the support for removal of the "X" prefix for instances in the generated DSPF is broken, and qrcfs fails with the following error:

[...]

ERROR (LBRCXM-609): Bad return status from QUANTUS run. 0xff00
ERROR (LBRCXM-709): *****  Quantus terminated abnormally  *****

Is there any way to overcome this issue? (we do rely on the removal of those "X" prefixes for ease of plotting nodes in post-layout simulations).

Thanks and regards,

Jorge.

P.S. I'm using ICADVM20.1-64b.500.24 and Pegasus 21.31-s008
