The profile list module cuts off long titles if the Limit Title Length box is checked. If you'd prefer titles not get cut off, leave the box unchecked. New profile modules will have the box unchecked by default.
If the Limit title length box is selected, the field defaults to 10 words before cutting off the title and adding an ellipse, but you can enter any number you believe will not cut off the title.
In the future, we plan to add a value that will allow you to choose to always use the full title. Until then, using the Title word count custom value is your best option.
With the release of Core v1.35, you can now display full titles. This option is enabled by default for new profile modules, but existing modules will need to be updated by unchecking Limit Title Length.
