Canada ETA HELP

So I applied for an ETA for my Mom (Irish citizen, no bad travel hx etc) which got approved instantly but in the confirmation email it says my name. I realises that where you have to add your signature at the end of the page (it says ‘exactly as it shows on your passport’) I wrote my name instead of my Moms. Now the ETA confirmation says my name but my moms passport number. Im surprised it even got approved like that. But now Im concerned it will be an issue at boarding because there will be an obvious discrepancy with the name on the ETA and on the passport. I submitted another ETA with everything correct but havent received a confirmation email yet (its been 2 hours)- Im worried this might be an issue. I also submitted a request on the IRCC webpage.
Would anyone be able to shed light on this matter? Plsss
