Right click on the local transaction and select "Remove".
After that, go to "Send" tab and make your transaction again. With more fee this time.
For making the new transaction, enter the address you want to send the fund to in "Pay to" field.
Click on "Max" or enter the value you want to send in "Amount" field.
Click on "Pay".
In the new window, click on "Setting" button at top right corner of the window and check "Edit fees manually".
Enter the fee rate you want to use for your transaction in "Mining fee" field.
Set it to at least 8 sat/vbyte. If you want your transaction to be confirmed fast, set it to around 13 sat/vbyte.
