AWS System Manager package and association

Hello,

I created a package in AWS system manager distributor and when I try to install it with "Install On schedule" option, i have the following error message in the parameter part: Cannot read property 'action' of undefined

If I try to use state manager directly and create an association with AWS-ConfigureAWSPackage, i received this error in parameter "Cannot read property 'MofsToApply' of undefined"

the only way to install the package is using Install one time option...

Do i have missed something?
thx
