When following the env documentation for PARPE_NO_DEBUG, exporting and sourcing this env does not disable if set to 0 or anything else other than 1.
Env sourcing example:
<parpe_envs.sh>
# some other exports here
export PARPE_NO_DEBUG=0
source /path/to/parpe_envs.sh
Setting this to 0, LOGLVL_DEBUG messages in the output log file are still suppressed. This is true even after a re-source of the envs and/or recompile of the parPE and paired amici models. The only way to return the LOGLVL_DEBUG logs is to remove the env var entirely / comment it out. It would make sense to me that setting the value to 0 should also accomplish this, but it does not.
