No brain map during the denoising step then ERROR before 1st lvl analysis
I have seemingly successfully imported an fMRIPrep dataset with 2 sessions of resting state. I added ROIs, set up 2nd-lvl covariates, and applied the smoothing preprocessing step, then pressed "Done" under setup.

Opening the "Denoising" tab I can see the distributions and the BOLD time series but not the brain map that is usually in the lower right corner. After pressing "Done" under this tab, 1st lvl analysis tab unlocks. However, opening this tab an error pops up:

ERROR DESCRIPTION:

I have followed these steps twice already, including importing but the same error occurred. Please let me know what I should do. Thanks.
