Subpanel are not displaying properly on screen

SuiteCRM: Version 7.13
PHP: Version 7.4
Theme: SuiteP
Browser: All

I need help to fix the below problem. When we reduce size of screen and when it is almost medium size screen(above 990px). Subpanels are getting out of table frame. See below image.

Thanks in an advance.


/* subpanel scroll button */

.collapse, .collapsing, {
    overflow-x: scroll;
    overflow-y: hidden;
