Can you provide a screenshot of how the font looked before vs. now? Also where can I observe that in the project you already provided? In terms of generation settings, you should typically aim for a Sampling Point Size of 72 or above with padding of 10%. By default I normally use 90 Sampling Point Size with padding of 9. The atlas size is a function of the number of glyphs you need to fit in there. Most of the time, you want the atlas to be a maximum of 2048 x 2048.
