Q Jocatt Kaplan

In que, a part its written that

“On 1 December 20X1, Jocatt acquired 8% of the ordinary shares of Tigret for $4 million and recorded it as a financial asset at the cost of purchase. This investment was designated to be measured at fair value through other comprehensive income.
On 30 June 20X2, Jocatt acquired a further 52% of the ordinary shares of Tigret and
gained control of the company.”

My confusion is that
In answer when there is Fair value change for investment on the date of additional 52% shares purchase the gain of 1m (5-4) on FV to 5m of financial asset should be transferred to OCI but in answer they have transferred the gain to P&L
Please explain this

Thanks
