Why am I getting a weird dialog with a red cross when I select Flashings?

Fix a Flashings error that shows a weird dialog (with a red cross) by removing an invalid flashing line type and checking for an incorrect [END] entry in Linestyles_V6.csv.

🧩 What’s causing this?

This problem was caused by attempting to define an additional flashing type at the bottom of the flashing line type list.

✅ Fix 1: Remove the offending line type

  1. Go to System Preferences

  2. Select Set Line Styles

  3. Remove the offending line type


✅ Fix 2: Check Linestyles_V6.csv for an incorrect [END]

Also spotted where someone put an [END] at the bottom of the Linestyles_V6.csv file and that caused it to crash.
