Hello,
The box you are checking is for internal transfers. If you want to disable admin confirmations for withdrawals, you must uncheck the box that is titled “Admin condfirmation required” under the “Withdraw transaction confirmations” section.
About the [wallets_transactions] shortcode, it seems your theme’s CSS is causing some trouble with it.
1. Could you please confirm that the problem does not show when you change to another theme?
2. If you like, I can login and maybe come up with a few CSS rules that you can add to fix the display issue. Email me some credentials if you want me to look at this.
3. You can also try out the alternative template, [wallets_transactions template="rows"].
Let me know please.
with regards
