Custom sidebar display bug in sidebar elementor widget


I registered custom sidebar (widget area) in functions and displayed it with sidebar elementor widget. It worked ok for a long time but today it began to display notices inside widget tag elementor-widget-container:

Notice: Undefined index: jupiterx_show_widget_title in /home/c/contorra/ on line 475

Notice: Undefined index: jupiterx_show_widget_badge in /home/c/contorra/ on line 476

Notice: Undefined index: jupiterx_widget_badge_content in /home/c/contorra/ on line 477

Other sidebars work fine, only one custom registered shows this.
