v2.0.0 Clash with Element Pack Pro

Hello… Since updating to v2.0.0 there seems to be a clash with the Counter widget from BD Themes Element Pack Pro. The front-end displays the following error:

Warning
: Undefined array key "_ob_use_tabbr" in
/homepages/0/d337033193/htdocs/clickandbuilds/Florence/wp-content/plugins/ooohboi-steroids-for-elementor/controls/ooohboi-tabbr.php
on line
72

Any ideas, please?

Cheers,
Andy.
