Key not showing expiration date in key list overview, only individual key detail view

Today I bulk uploaded a number of keys into a list. While verifying the results in schleuder-web, I noticed one user's key is not showing its expiration date in the key list overview despite it having one. I've attached (redacted) screenshots showing this behavior.

Overview: key-overview

Detail: key-detail

This user's key could be considered a bit "unique" compared to most other user's keys in that the master key is 2048-bit and it has 2 sub keys - 1 of which is an expired 2048-bit key & the other is an active 4096-bit key.

The key works fine in schleuder, it just appears to be a cosmetic/display issue in schleuder-web currently. Although I'm not sure if it would become an issue after the active key(s) expire in 2021 depending on how schleuder detects key expirations.
