There could be a number of things.
Firstly, is the architects name text a different colour to the other text?
your colour dependant plot styles could have the line thickness of
the architects name text colour, thicker than the rest.
Change either the layer and/or colour the architects name text is on (hopefully its set to bylayer) or change the line thickness in the colour dependant plotstyle.
secondly, Text Format. is the font the same as the rest? you may find
if you go into Format>text style, the text has bold applied to it.
Hope these help. Get back to us on how you go.
