It's not a reminder, it really activates the next chapter. When you consume the item it grants you access to the chapter. However, you still need to complete all prior parts of the chain.
Check your completed quest log to find which chapter you've finished. Then consult the lotro wiki to find out where you need to go next. Sometimes you need to go to your allegiance hall for the next phase, sometimes you need to meet the faction representative somewhere out on landscape.

The above mentioned part of the wiki details the quest chains for each allegiance. Figure out how far you made it into your own progress, then consult the relevant quest chain and make sure you completed each objective step.
Many fail, Such Kludges, So LOTRO
