Automation Assign Sub-tasks box literally only show half of a letter when writing the name

I do not know what are the process thoughts behind this design, or whether I am the one who does not know how to fix this. But when adding sub-task assignment automation, I basically can't see what I am writing into the sub-tasks (as seen in the attached image).
