Magento 2.3.5 Error Exporting Customers

NO AUTOMATED RESPONSES!! Dont just say I have read your project and I am a good fit. You will not be chosen. I have had bad experiences with people that were not qualified for the job. Looking for a certified Magento Developer. When you respond, provide details explaining how your skills fit this exact project. Thank you. When I attempt to export customers from the customers grid in Magento 2.3.5, I get an error. Exception #0 (Exception): Notice: Undefined offset: 0 in /chroot/home/****/vendor/magento/module-customer/Ui/Component/DataProvider/[login to view URL] on line 171 This error only occurs when there is a customer that was created in the admin is included in the export. If I filter out the admin created users, the export functions correctly. I used to have the store set up as a multi store configuration, but we deleted one of the stores so there is only one store in our installation now. We also switched the store to single store mode and ran into some problems so we switched back to not single store mode. I think when we switched single store mode on and then off, the problems started.
