A new icon appearing in my input operators

Hi everyone,
Here is my issue. I created a first design sequence and published some geometries. These geometries are properly published, and I use them as inputs in a second sequence (the boolean structure is correctly set to true). A few days later, when reopening my sequence, I find a new icon to the left of all my imported elements (see screenshot). This blue cross is also present in my construction tree under the 'published geometries' tab of my previous sequence. I’m wondering about the nature of these blue crosses because they don’t seem to block my sequence (no alert messages), but it seems like updates are no longer happening in my two linked sequences. When I modify sequence 1, the published geometries stay the same, so my sequence 2 outputs the same result. The crosses disappear if I change the input data of my sequence 1 or if I copy-paste it into a new 3D shape. Do you know the issue and is there a better solution to remove thoses crosses?

Thank you in advance.
