Conflicts with Other Plug-ins

First of all, please understand that I use a translator due to my inexperienced English.
If you enter the shortcut code of the [TablePress] plug-in in “Filterable Gallery – Gallery Items – Item Content”, the table displays well, but the category designation or search function of “Filterable Gallery” does not work.

So I asked the manufacturer of the “Filterable Gallery” plug-in, and he answered:

And the error “Uncaught TypeError: p.splice is not a function” shows: because you are displaying Table data by using a shortcode. Actually, the Filterable gallery converts all data to JSON format. But when we add Table data using a shortcode then that data can’t convert as JSON format. And that’s why it is showing an error. But if you manually create a table by using HTML tags then it will not show any errors. So you can ignore this error. Hope you understand.

The reason I loved [TablePress] was that it was automatically synchronized when I entered the shortcut code, but unfortunately I didn’t get the solution I wanted from him.
Please let me know if you have a solution.
Thank you!!!!!
