Can Not Change Game Mode without Closing & Reopening BF6

PS5 : Ok. Let's say I decide to play Ice Lock Conquest after first opening the game ..  👍 It allows me to select and play as you would expect 👍. However If I decide to play any other game type after selecting this they are all greyed out and will not select no matter how many times I press X . I have tried to press ∆ but this just opens the lobby with the previous game mode selected. This has only just started happening since the Winter Offensive update. Some kind of Bug ??? Anyone else having this issue ? I have to keep closing and reopening the whole game to change modes.
