IF you add enough profanity filters you can no longer see your list as only the first ones are shown but pagination doesn't seem to exist to show the remainder.

Am I missing something?

Can't add more profanity words because of this :-(

I reckon that is more likely your theme at fault here, as I've got over 100 entries on my test site and a) I don't have a scroll bar like you do and b) I can still "add profanity" by clicking the relevant button.

Do the following in the ACP - click the 'Signed in as ........' drop down, click 'AdminCP Theme' and change the theme to the default IPS theme.

Does the issue still occur? If so, raise a ticket.
