You want to check the bank conflicts against the L1 Wavefronts Shared Excessive instruction-level metric on the Source page, as mentioned in this post. If this metric has any non-zero values on the Source page, that is where the bank conflicts are originating from. You can select the metric for navigation and use the buttons on the top to jump to the row with the highest, lowest, etc. value.
The values shown in your screenshot snippets don’t immediately make sense to me, but it’s not possible to debug this further without the actual report. You could check on your end if the data shown in the SASS view of the Source page for the SASS instructions correlated with these high-level source instructions are more consistent.
