Unable to add asterick in column label in JDE 9.2.26.1 using form extension/personal form

Hi All

In JDE 9.2.26.1 , I am trying to rename the label Business Unit Type in P0006 to Business Unit Type * using personal form/form extension. The moment I add the asterick and click tab to come out of the lable , the asterick disappears. It adds me to allow other special characters like & # _ etc but not asterick

Is this normal behavior?

I tried to use 'Mark As Required' option but the blue asterick doesn't appear against the column.

Please share your thoughts

Thanks in advance
