Problem with "Full Stop" or "Period"

Hi, I need help… I am trying to create the full stop or period as " . ". When I test it with Microsoft Word so I typed “.” for more than one like: “…”, but it kept disappearing after typing two “.”.
Other fonts are working fine but just period or full stop. What can I do?

Check if this happens in other programs like Wordpad. Probably it is Word’s autocorrect converting .. to … (elipsis) which is not defined in your font. See this list of recommended glyphs for body text fonts.
