You have set everything up correctly, except for a very important thing.
You made your plotfiles for a different address (plots are tied to specific Burst addresses). The one you made the plotfiles for is:
Account - BURST-FWVS-V6V8-9XLV-2YFTA
Numeric ID - 316869188929385336
So, in order to not have to plot again, you need the passphrase for the above account. Then you need to go in and change the reward recipient for that account.
If you don’t have the passphrase for it, you will need to use the account you showed in your post above (BURST-LZ2W-WECH-JJEF-4UDWQ with numeric id 3130418331727264796) and plot again.
