Emodgies dissapeare from Live Page Builder elements after saving

[ScratchyCat3]

Wordpress 5.8
Live Page Builder 1.5.10
I used emodgi in titles of accordion items, but now they have disappeared. I still can add them and even confirm changes and publish the page, but if I close Live Page Builder emodgi are gone. Tryied to use them in accordion titles, content and in simple text element - all the same.

Emodji can be used in standard Wordpress editor.
