Anchor Link Text Changes Do Not Show

Hi. Very quick question concerning styling using the Fixer template. We've gone to the main settings, Anchor text and Anchor Hover text settings. Changed the weight to bold, expecting to see site wide changes. Nothing happens or updates - seems to be showing as default weight. Colour changes work but the weight of font for a link remains unchanged? Assumed that editing these main styles would work without having to edit any core CSS surely?

Also, edit a block of text using Upfront, add in a link and no global link style is applied. No change of weight, colour or roll over effect. When we edit the text, apply a colour change and increase the weight to bold the link retains the new colour but no rollover effect shows.

Are we missing something?
