Trying to insert external link on campaign, but it glitches

[QOMO]

I am trying to link to an external site through the text on a campaign, as our campaign scheme only allows for linking to collections.

Though, when I am inserting the external link on the text, the whole section glitches. I have attached photos showing the glitch, and how it looks when there is no external link set on the text. 

Is there a way to fix this? Or maybe some way to code the campaign liquid file to include a section for external linking?
