How to separate circles with the split tool?

[rmzbr]

Please, can anyone help me?
I'm new to affinity and it was love at first sight.
But I am having a problem that I reported in the attached video.
When trying to split the grid circles, they go wrong, is there anything to fix?
The grid shown is for the next heart.

Hi rmzbr,

Welcome to the forums

Could you please upload a copy of your .afdesign file so I can look into this for you?

This is kind of a nonsense set-up (maybe AI driven by its wondrous shape-builder tool) as 3 circles don´t count into the heart-shape (cyan+red) - and it´s not very precise.

Warning macOS crashing bug ahead: Here´s a copy with „touching“ circles. Select all except the cyant circle and Divide - from the result select the biggest parts left and right and delete - select everything except the cyan circle and call Boolean add = crash. macOS held hostage try to force quit AD if you can.

I don´t get why you not just use the heart-shape and do some Boolean subtracting a circle from it and adding a second circle:

Thanks for your report, I've duplicated and split this into our bugs on Mac section for our QA to check and log this with the devs, you can find this post here - 

Your suggestion certainly seems like a better option here, thanks for your input
