Got 5k coins for a Rivals objective, added, than it disappeared

Had a Rivals game objective to score the first goal for 5k coins. Did it, got it. Im up 13k from 8k.

then opened the teansfer block, looked around, did nothing, and the 5k disappeared, im back to 8k

attached the video, watch the top right corner, its just disappears.

i would like to get back that 5k + interest for my troubles. Things like this should not happen. Fix is.
