You've probably not re-installed, configured or upgraded the add-ons providing those missing functions, or they have changed their locations during the upgrade.
The screenshot above i got it from the internet (https://www.google.mu/search?q=jira+7.4&source=lnms&tbm=isch&sa=X&sqi=2&ved=0ahUKEwj4qPOKvP7UAhUSJFAKHY4BBucQ_AUIBigB&biw=1366&bih=638#imgrc=3Y3zQuw_Cb_KTM:)
Is these 2 icons are on addons or when upgraded they should be their by default?

I don't know what those icons are, but they're not core to JIRA off-the-shelf, so they're being provided by some add-on you've got.
Without knowing what add-ons they are, I can't tell you a lot more.
