@gestaltakademin: You seem to have added CSS code due to which the testimonial box is showing up larger.
Go to => Appearance => Customize => Additional CSS and remove the following CSS Code.
#testimonial-section .entry-content {
height: 700px !important; }
}
To align the boxes in courses, events and testimonial section what you can do is use the Excerpt Option.
Go to => Dashboard => Posts => Edit your events, courses and testimonial posts => On the top right corner you will find Screen Options click on it and check Excerpt box. Now you will find an Excerpt Box at the bottom of your text editor. You can now insert custom excerpt so that all the post box appear in an uniform manner.
Let me know if this helps you out!
Kind Regards,
