blue text after bollon in drawing turns to black once generating pdf

Hi guys,

As attached, I have picked up the bollon from the drawing by clicking, and I applied all the text into the "note" layer. They all blue in color in the drawing, but when I pdf the drawing, any text after the bollon turns black. As far as I take the bollon away, all the text shows black in the pdf. I have checked all the settings and they seems all correct.

Can anyone please help?

Thanks in advance.
