Shortcodes for PHP Files

I have a plugin called Sweet Custom Dashboard that actually allows me to add content and media to my dashboard for my users. It requires me to actually go into the plugin and modify a php file and then the changes reflect in the wordpress dashboard.

I tried inserting the Appointments + shortcode which would display my availability and for some reason when I do it, everything is distorted and all the formatting is gone... colors, clickable buttons, functionalilty, etc.

I"m not sure if it's a coding error on my end or something with the plugin itself. Here is the code I used within the custom dashboard php file.

<?php echo do_shortcode('[app_monthly_schedule worker=6]'); ?>
<?php echo do_shortcode('[app_confirmation]');?>

I also attached a printout of what the dashboard looks like after the shortcode is in... notice the distortion.
