Error messages, Use of uninitialized value, when running script v236

I am getting multiple error messages when running the script version236.

error messages -

Use of uninitialized value in concatenation (.) or string at C:\vmscripts\vmwarevSphereSecurityHardeningReportCheck.pl line 4142.

also line 4145.

Use of uninitialized value in pattern match (m//) at C:\vmscripts\vmwarevSphereSecurityHardeningReportCheck.pl line 3764.

also lines 4003

I am running -

vmwarevSphereSecurityHardeningReportCheck.pl --server <ESXi host 5.0.0 469512> --username <> --password <> --recommend_check_level profile2 --csv yes

I do get a valid html output, but am concerned i am missing something.  Please advise.
