A: the text mask can be made by two ways: command TEXTMASK and in-place mtext editor. You need to know which way made it then choose the right way to remove it.
How to judge: double-click the text, if there is in-place text editor, then it is made by MTEXT editor, or else it is made by TEXTMASK.
Solution:
If it is made by mtext editor, then cancel it by mtext editor.
If it is made by TEXTMASK, then use TEXTUNMASK to remove it.
