User defined bookmarks in SAC stories not longer working

Dear community,

after the upgrade from weekend to release 02.2021 we observed that the filtering of dimensions in exploration views are not longer working. (See screenshot). Data is coming up in that example in table but the header line all additional dimension filtering are blanked with the sign {}.

There was no information sent out that bookmarks or saved views for exploration views are not longer working after release upgrade. Is there sth. we can do to reactivate it ?

Thanks a lot.
