Hello,
my website displays also a PHP warning about undefined array keys. In the Customizer it ist always displayed, in the editing mode in Elementor only when opening the demo page for the first time and on published pages the error is displayed at irregular intervals. (even though the page is always opened in the same browser on the phone or laptop).

Elementor version: 3.18.3
Theme: Mestc (from Design Grid)
PHP: 8.3

Error:
Warning! Undefined array key “margin_tablet” in /home/.sites/459/site2723775/web/wp-content/plugins/elementor/core/files/css/base.php on line 778 Warning: Undefined array key “margin_mobile” in /home/.sites/459/site2723775/web/wp-content/plugins/elementor/core/files/css/base. php on line 778 Warning: Undefined array key “padding_tablet” in /home/.sites/459/site2723775/web/wp-content/plugins/elementor/core/files/css/base.php on line 778 Warning: Undefined array key “padding_mobile” in /home/.sites/459/site2723775/web/wp-content/plugins/elementor/core/files/css/base.php on line 778

What I have tried to fix the error:
1. clear cache
2. plugins were deactivated one after the other except Elementor (but the bug was still there)
3. changed theme to Elementor Hello (the error disappeared and when I switched back to the Metsc theme, the bug was there again)
4. contacted theme author with the feedback that it is an error of Elementor.

I hope you can help me to fix the problem. Thank you very much.
Best regards
Michelle
