Why is adding a No Couple Relationships fact making name disappear in Landscape view?

I have just added No Couple Relationships under Facts in the Other Information sections of three siblings. The unexpected behaviour affecting just one of them is that it has now made her name disappear from Landscape view. See https://www.familysearch.org/en/tree/pedigree/landscape/L8WG-RXP . Her ID is LDFZ-S47. If I delete the added "fact" the problem disappears. Any ideas why my actions appear to be causing this problem just with her?

Update - to make the issue a little clearer (and avoid using the link) here is a screenshot to illustrate how her (only Kathleen's) name is being cropped out of view since I added identical "facts" to her and siblings Aubrey and York:
