Match types don’t apply after moving to “Create Ads” step” in Google Ads


I’m trying to set up a Google Ads campaign. On step 2 "Set up ad groups" I add keywords to Ad groups with match types:

+ipad +apps
"ipad apps"
[ipad apps]

Then I click "Save and Continue" and on Step 3 my keywords appear changed to:

ipad apps, +ipad +apps

Then I click back to Step 2 and I see the following:

ipad apps
ipad apps
+ipad +apps

For some reason, my keywords are changed to "broad match". How to prevent this behavior? What do I need to do to turn on Matching Types?
