Error: Unknown format specifier "v" after login

Hi there,
we are using latest version Joomla 4.2.5 with EasySocial 4.0.12 in combination with PayPlans 5.0.6.

We have defined menu items
EasySocial - Pages - All Pages Layout (Access: Public)
EasySocial - Dashboard - User Dashboard Layout (Access: Specific User Group)

A visitor can access the EasySocial Pages without issues.

But when a registered user logged in with his/her account, he/she is getting error on both menu items with message: Oooppps - Error: Unknown format specifier "v" after login

I do not know what the problem is, because this error started to happen only after latest Joomla Upgrade to 4.2.5 and EasySocial to 4.0.12. There was no issue before the upgrades and both pages were working as expected.

Can you please take a look on this.

Thanks and regards
Markus
