Finsweet CMS Slider inside a Tab module

Huhu Finsweet checkers,
I implemented this finsweet slider (Example1 - CMS Slider) to the following website: Alessandra Piazza | Goldschmiedin München
(inside a tab module)

If I load the site, the slider content gets loaded for the default tab (no matter which one I choose). Clicking the next tab, the slider content gets loaded BUT NOT THE RIGHT AMOUNT OF SLIDES IN IT! If I start the inspector or resize the browser window, the right number of slides get suddenly loaded (you can see this on the dark slider nav dots I unhided). What am I missing here? Any Ideas?

Here is my site Read-Only: Webflow - alessandrapiazza1
