Event controller misreading assembler inventory %

Greetings, while experimenting with event controllers I came across a troublesome issue.

The issue is that, as the title mentions, the event controller does not read the inventory correctly with changing contents.

My testing was done on an un-modded, new save of the Red Ship v2 world with no plugins installed.

To reproduce, place an event controller anywhere on the station and follow the below.

Event Controller: Event: Cargo Filled %

Condition Equal or Less (Not relevant to the issue)

Threshold: 0% Block: (Assembler of choice)

And Gate: ON (Not relevant to the issue)

Now, keep an eye on the two cargo fill percentages. Place an item, in my case 1.25k Cobalt ingot into the top inventory.

Both bars jump to 3.5%.

Now place something, for testing 15 medical components into the bottom inventory. Both bars jump to 60%.

Now remove the medical components from the bottom inventory. Both bars drop to 0%.

Due to this, the event controller outputs a false positive.

I did not see any previous reports about this, my apologies if this is a duplicate.

Edit: With further testing and discussion with folks on the discord, it appears the issue is purely in the terminal, with the blocks proper functionality remaining as expected.
