Convert Record by Workflow not triggering custom functions in Potentials set for "record create"

Convert Record by Workflow not triggering custom functions in Potentials set for "record create"

Hello

I have a series of workflows in potentials that do various things on "record create" when a potential record is made after convert from leads.

The workflows in potentials module seem to work fine when the conventional convert button is used in leads. However when I use a leads workflow to convert a record to potentials. it doesnt trigger the custom functions in potentials which are set for "record create". 

I fully understand that workflows dont trigger workflows, but surely when a workflow in leads creates a new record in potentials then all workflows and custom options should work in the potentials module that have been set to operate on record create.

Has anyone else experienced this issue, or can anyone suggest a fix?

Thanks

Tim
