For the installation guide for this app https://appexchange.salesforce.com/servlet/servlet.FileDownload?file=00P3000000P5pYYEAZ) it looks like there is additional configuration required for it to work work with custom objects.
"Adding the Timeline to other core objects and custom objects is almost as easy as adding it to Account, Contact, Lead, Case and Opportunity page layouts as described above. The one additional step is to create a Visualforce Page that embeds the Timeline component and uses a standard controller for the object type in question."
See page 14 of that guide for the additional steps.
