Three ingredients placed on a table in the upper exterior cell at Darklight Tower shouldn't respawn because the rest of the location is a no-reset zone. Their encounter zone setting should be DarkLightTowerZone like other items on the table.
Also, the two deathbell flowers may be placed too close to the soul gem and the frost mirriam may be placed too close to the potion, depending on what size/type spawns from the dummy markers.
These three ingredients were added with Skyrim SE, which is related to why the problems exist.
