functional segmentation misalignement

Hello,
I am currently working with 7T functional MRI data (resolution 1.25mm3 & T1 resolution 0.65mm3) - CONN(22.v2407) in Matlab R2024b. 
I am using CONN's default preprocessing, which I adjust to fit my data.


However, this is now the second time I have run the preprocessing and ended up with a misalignment between the segmentations and my functional images.


The first time, I started from the original data and performed segmentation on all anatomical and functional data.


The second time, I only reran the preprocessing on the original functional data, thinking it was a segmentation error affecting the functional data.


How can I move forward with this issue?
Notably, when I launched the setup before the denoising step, I ended up with an aberrant result in the denoising section, as the segmentations were misaligned.


I don't understand what is happening.
Thank you for your help.
