Name Text In Detail View Not Displaying Correcly For One Module Only

Good morning,

Following an upgrade to v10.0.2, we have a bit of a weird issue where the Name field text isn't displaying correctly in a custom module and looks like the below (you can just make out the text):

On edit, the text is visible:

However, every other module, both standard and custom, display correctly:

Has anyone ever seen this issue before and would anyone have any ideas about what could be causing this issue? It seems to be module specific but I can't see anything obvious in the module's files.

Many thanks,

Ian
