@BigWheel I understand the "why" of the period in Linux (and Unix which was my first exposure to non-mainframe operating systems) but except for the few people that use Linux command line they are not needed. In fact they are visually confusing to those of us that extensively used operating systems that used the period for one and only one purpose, to separate the filename from the extension. In early versions of many operating systems only one period was allowed in a file name.
I "think" that changed at about Windows 98 but it could have been earlier or it may have been XP.
But My point was that the periods are now non-standard, except for separating file names from extensions and generally should not be used even though Plex is supposed to ignore them. Also some Windows programs (and implementations) still get confused by superfluous periods.
So, unless the OP is one of the few that still use Linux command line utils and have trouble with escape characters I still recommend the removal of unnecessary periods particularly if the files are to be shared or used in other operating systems.
But is does not matter too much as it is mostly just aesthetically better for many folks.
What does matter is the naming, spelling and structure as I outlined above.
