What did you do?
I have an automated platform orbiting Nauvis called "Fulgora Shuttle" with Electromagnetic Science Packs.
On Nauvis, the Landing Pad has a request for some positive amount of Electromagnetic Science Packs

I have made sure:

• The shuttle is in 'automatic', orbiting Nauvis, with 'Unload' ticked
• The shuttle has Electromagnetic Science Packs
• The Landing Pad requests a positive amount of Electromagnetic Science Packs
• The Landing Pad has >6 landing pods available and plenty of storage space. No other Pod traffic disturbs the setup.
• The Shuttle has no logistic requests for Electromagnetic Science Packs from Nauvis for itself. So this is different from viewtopic.php?p=665499
  Note: it has requests for Electromagnetic Science Packs from Fulgora, though

What happened?
The "Fulgora Shuttle does not drop its Electromagnetic Science Packs
Even deactivating all logistic requests doesn't trigger the drops.
Manually dropping all Science Packs works.

What did you expect to happen instead?
The "Fulgora Shuttle should not drop 6 pod's worth of Electromagnetic Science Packs

Does it happen always, once, or sometimes?
This shuttle conistently gets stuck at Nauvis
However I have another shuttle, the "Vulcanus Shuttle" with the same setup but for Metallurgic Science Packs
This one comes and goes, and always fulfills the requests for Metallurgic Science Packs from the Nauvis Landing Pad.

Did you mix up "Production science pack" icon with "Electromagnetic science pack" icon?

Cargo landing pad on nauvis:

Welp, that is embarrassing.
Tank you for spotting what I could not (for days )!
