URL Link being replaced by a string of asterisks.

When editing the Publications page (https://allencenter.tufts.edu/our-research/publications), I noticed that the URL for a citation is being partially replaced by a string of asterisks.

For the 2020 publication citation ‘An in vivo brain-bacteria interface: the developing brain as a key regulator of innate immunity’, the desired URL [https://www.nature.com/articles/s41536-020-0087-2] is switched to [https://www.nature.com/articles/s****************.] This URL points to a different article.

I have tried correcting this URL in “Visual” and “Text” modes but it reverts back to being partially replaced by a string of asterisks each time.

I would appreciate any help with this!
