Tables created with all lower case names

Upon installing the plugin today, various tables were created with the names all in lower case letters. Since the code makes calls to these tables with at least one upper case letter, that call fails. For example, the table wp_coreftcalendar_calendars is created, but the code would read/write to wp_coreftCalendar_calendars
The database is MySQL 5.7.

It was simple enough to rename the misnamed tables, but I have no visibility on what else might have failed during installation due to these errors. Since reinstalling the plugin from scratch is likely to simply reproduce the same problems, any other advice in sorting things out would be helpful.
