Hello,
On Joomla 4.4.3,
for Advanced Module Manager Joomla updater notice 10.0.21 Free is a new potential version for 10.0.21 Pro.
It was the same for 10.0.19 and 10.0.20.
So on dashboard we have a warning about 1 extension to update ...

What do you mean by "rebuilding the update sites" ??

Ok found it !

And now it's ok, thx !

Hello,
I still have the problem.
Updater announce me new pro versions despite i have already installed it.
And this, even if i rebuild update sites.

And this happen only for your extensions.
There is a problem somewhere.

For now i fixed the problem by re-doing extensions update with Joomla Updater.
Next time it happen again i'll give you access.

Whetever if Update by Joomla updater fix the problem perhaps your updater miss some data update somewhere.
