Despite the fact that I am high enough in my grand company, I have twice the amount of gil to purchase the plot in Lavender Beds, I am being told that I am NOT allowed to buy it! It tells me that I cannot purchase the plot

It seems like the game either does not recognize that I am First Storm Leiutenant or it does not register that I have 7 million gil for a plot that costs 3.5 million

Does anybody know what the problem could be?
