Quick answer: Write the enum value using the name the importer expects (display name or the full value name), and make the enum a UENUM with explicit entries.
Your DataTable rows all show the first enum value no matter what the CSV says. The importer could not match your enum text to a value, so it defaulted. Use the exact expected enum name format.
How to fix it
1. Match the expected enum name
Write the enum value in the CSV exactly as the importer expects, typically the display name; a mismatch silently falls back to the default enum entry.
2. Declare a proper UENUM
Ensure the enum is a UENUM(BlueprintType) with explicit named values so the importer has a name table to match the CSV text against.
3. Verify with the import log
Check the Output Log during import for warnings about unmatched enum values, which tells you exactly which row and string failed to parse.
Catching the ones you can't reproduce
The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.
Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.
This is where a tool like Bugnet earns its place. Its SDK captures every Unreal Engine error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
Most of the time the fix is small. Seeing the failure clearly is the part that actually costs you.
