Problem with Velo A side during run 63757

While studying the event occupancies with trigger type TechnicalTrigger, which is synchronized with bcid 900 or 902, I came across run 63757 with showed events with large Velo multiplicities while normally in these random triggered events, occupancies are very very low, only noise hits. Apart of bcid 902, also the other events taken with physics trigger show the same feature, see below.

In the logbook, I only find:

  3736   11-Dec 19:38 63758 LHCb Continuing the series of 5Kevents/run for SPD time scan and VELO powering.

Maybe this run should never made it to the production ?

Does this problem also appear in other runs ?
