Sorry to bother, but I was wondering if anyone could help. I'm relatively new to type design, I've only been at for like 8 months and self taught, there's much I don't know. I thought I had finally finished my first font, but some issues were found (please look below). I have no idea what that is or how to fix it. I also couldn't find anything about LTSH and VDMX tables in Fontlab, I might not have looked hard enough though. Any help would be appreciated.
• in the LTSH table many (almost all) values are incorrect, some seem to be really massively off (https://docs.microsoft.com/en-us/typography/opentype/spec/ltsh)
• in the VDMX table many (seemingly all) values are larger by one unit than needed (https://docs.microsoft.com/en-us/typography/opentype/spec/vdmx)
. This may be responsible for the error report regarding vertical metrics.
