The Unified Runtime sync-points used to represent SYCL-Graph edges are not correctly implemented for the Level Zero adapter. The L0 events used to implement them are not reset to the non-signalled state after an enqueue of the graph. Fixed in the UR L0 adapter change oneapi-src/unified-runtime#965 which resets the UR events to the non-signalled state at the end of the L0 command-list.
