Array index offset - notices in the apache error.log

Hi,
Inspecting the Apache error log, I have numerous index notifications crashing the array.

These warnings occur when there are visible blocks interspersed with hidden blocks, which triggers the apache warning, due to the invalid index in the array.

Below one of the log entries and a print of related course.

Ps .: I'm using Moodle 3.8, with the latest version of Tiles. Even after the update, the warnings continue.
