Main Menu Links taking users to FTH site

if it happens again, please note the exact conditions.

It just happen after visiting the site just now. I typed in btoasty.toastmastersclubs.org and it took me to our site correctly. However when I click on "Home" on the Menu panel. It took me to here:
www.toastmastersclubs.org/welcome/?zp06
When I hover over the "Home" on the Menu panel, the pop-up that lets you know where it will take you shows:
toastmasterclubs.org
When it is working correctly; when I hover over the "Home", it shows:
btoasty.toastmastersclubs.org

Thanks,
Rick

1) what browser and version are you using?
2) What operating system?
3) are you using a proxy server or VPN?
4) what security software and version are you using?

1. Last night I used Chrome Version 86.0.4240.111 (Official Build) (64-bit). But this also happen on the same PC running Edge Version 86.0.622.51 (Official build) (64-bit). This also has happen running on different PCs as well.
2. Last night's PC was running Win10 64.
3. No proxy server or VPN on last night's machine. One of the other machines listed in #1 was under a VPN.
4. Just the default Window's security. No other virus protection.

Was the "different PC" in the same location?

Yes, using the same Wifi with one going through a VPN. If this is an issue I'm just having on my end, that's fine. I'm just not wanting our visitors to our site having these issues. Thanks.
