Bug: The menu always prompts me to complete auto rifleman training

[Tabarnaco]

I finished the automatic rifleman training and got Expert, yet no matter how many times I do it the ♥♥♥♥♥♥♥ menu prompt doesn't disappear (the new training available! thing). I just unlocked the Grenadier training, got Proficient on it and the alert disappeared.

Did you report to the Drill Sergeant after completing all trainings? After each station you'll find a Drill Sergeant near the closed gate near the rifle range.

I just recently redid my training and all worked well.
