Should I still be allocating cash to a high savings account from my monthly salary if I have already saved up for my emergency fund?

Have saved 10k after 10-11mths of putting away 50% of salary. Should I create a new account with gigantiq/Singtel Dash to save up the next 10k by allocating 25% to savings & 25% to investing or should I put the 50% of my salary from now on to my Stashaway investing portfolio?

I’m not attached at the moment but thinking of the possibility that I might need the money in short term eg 3-5 year should I have plans for marriage or BTO and incase my stashaway portfolio is losing money?
