update-PWFolderSecurity not found.

I am trying to add some security to a folder and I am getting  the below error:

PS C:\PS> UpdatePWFolderSecurity
UpdatePWFolderSecurity : The term 'UpdatePWFolderSecurity' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was
included, verify that the path is correct and try again.

get-help is finding the cmdlet:

PS C:\PS> get-help UpdatepwfolderSecurity -full

Name Category Module Synopsis
---- -------- ------ --------
Update-PWFolderSecurity Cmdlet PWPS_DAB UpdatePWFolderSecurity is used to add user(s), group(s), or userlist(s) access control to specified folders.
Update-PWFolderSecurityByUserL... Cmdlet PWPS_DAB UpdatePWFolderSecurityByUserListSwapWithWorkflow is used to replace existing userlists with another.

I tried re-importing pwps_dab:

PS C:\PS> Import-Module pwps_dab
Security Protocol now set to TLS 1.2
PWPS_DAB Version is 2.0.6.0
This is a 32-bit process.
WARNING: The names of some imported commands from the module 'pwps_dab' include unapproved verbs that might make them less discoverable. To find the commands with unapproved verbs, run the Import-Module command again with the Verbose parameter. For a list of approved verbs, type Get-Verb.

I even re-installed.

VERBOSE: Module 'pwps_dab' was installed successfully to path 'C:\Program Files (x86)\WindowsPowerShell\Modules\pwps_dab\2.0.6.0'.

"Missing something, I am..."

any ideas? 

all the other cmdlets I call seem to be fine(of course I don't use "ALL", but...)

Thanks!
