Missing text

done a test carve today on 12mm ply before using up an oak frame ( thankfully, lol ) i seem to have missing parts on the lettering, designed in easel, font - baskerville, 1/8 down cut bit, 2mm depth of cut, used easel recommended cut settings ?
first larger project i have tried to date, done a couple of small signs using a v bit which came out fine,

It looks like the font that would be missing is too small to carve with a 1/8th bit and would have to either do the whole thing with a smaller bit or do muitiple bit carve
