Joomla 4 Update Check for CK components and modules

I am starting to plan my migration to Joomla 4. When I run the pre-update check I get message 'Potential upgrade issues' against MaxmenuCk and other CK products. All the CK products I have are up to date.
What should I do about these messages?
See screenshot for the messages and products
Kind regards

Cedric,
From reading the forum message, the other user did the following:
1 Uninstalled the components/modules/plugins.
2. Did the update to Joomla 4
3 Re installed components/modules/plugins.
Is that correct?

NO
this is not correct. You must read what I have written not what other users do
check your versions :
- you are up to date (version at least the one listed in the forum) >> ok you can update to joomla 4, the extensions are compatible
- you have an old version >> update the extension, then update to Joomla 4

NEVER uninstall an extension unless you want to loose your data
