Red Mage VerHoly/Verflare Bug when synced

When submitting a bug report, please use the below template and thoroughly fill out the necessary information.

Date & Time: 7/14/2019 about 11:00 AM to 12:00 PM
Frequency: Infrequent
World name: Balmung
Character name: Karen Bright-flower
Class/Level: Red Mage 73, synced to level 50.
Party or solo: Party
Area and coordinates: Labyrinth of the Ancients
Steps:
1. Follow the red mage rotation until you do the enhanced redoublement combo.
2. Cast displacement.
3. Cast Acceleration.

Sometimes when doing the above in duties synced to level 50, I encounter a bug where Veraero and Verthunder are replaced with Verholy and Verflare. At higher level this would be normal, but because I am synced to level 50 when this happens, I am unable to cast Verflare or Verholy, and also unable to cast Veraero or Verthunder until the effect ends and the buttons on my action bar go back to normal.
