Disregard - figured it out. I had missed that my phone had updated and caused a database version mismatch. Rolled my PC version back and am updating.

Adding some information for anyone coming across this in the future: I couldn't figure out how to use Database Display plugin to convert a table, but the paste method described by @massivebox works perfectly after you temporarily disable the Database Display plugin. It will not work with the plugin enabled.

@mindarchr I appreciate you for this. I couldn't figure out what I was doing wrong given that my test exports in the user guide were working by default with markdown but my custom ones were not.
