I've created 5 shortcodes and everything works properly
Anyhow, when I add another shortcode the editor shows only the previous 5 shortcodes instead of 6. Actually the 5th shortcode disappears
If I add a further shortcode, the editor keeps displaying 5 shortcodes only, that is, the latest 2 that I've created and the first 3 ones
How can I solve the problem?
