For any file on the disk, open the "Change attributes..." dialog. Add the internal plugin "tc" with the field "writedate" for ex.
through the "More attributes" button on it. Surprisingly Initially the corresponding field is somehow empty?
Although it would be very logical for the value to be fetched automatically. After all, we are ALREADY working with the file.
We ALREADY know the value of the selected field. We just want to change this time now. But no. It doesn't work like that here

Then the next intuitive step would be to use the ">>" button. So yes, I press it and get a dialog where the value of the datetime
type, which we plan to change through the plugin, is already filled in. So far - so good.
Ok - we agree with this value, Or we slightly adjust it. For the essence of the described bug, this is not critical action at all.
The value is inserted into the corresponding field. And now we AGAIN press the ">>" button and with surprise instead of
the expected the same value, we get this: https://i.ibb.co/9PW4zHC/2025-05-25-112534.png
IF we will press OK - instead of the value which we just saw - finally we will see this: 01.01.9999 00:00:00 in the "tc"
plugin's VALUE field of "writedate".
reproducible on TC x64 but not on TC x86
****************************************************************
What else is unclear about the essence of this bug in principle. Why are these plugin's fields remembered when I click OK?
I didn't use the "F2 Load/Save settings" combo box ability here! So I did NOT want to see these fields the next time
I opened this dialog. But for some reason they show them to me again in this case.
IF I remove these fields, then I can fix this "clearing" only through the OK button, ALTHOUGH - at the same time, the code
is executed NOT only for this logic, but also related to working with other objects on the form of this dialog.
And if I somehow did something there, then instead of the ONE action I wanted - delete all the plugin fields from the scope -
I will also receive the set/clear/change actions for some property/field that was accidentally enabled/disabled by me...
The need for a "+" button on the form is also unclear. It performs the same actions as the "More attributes" button.
So why is the duplication of functionality done? Or are you saying that for some reason I'll install the plugin I need faster?
This is definitely not the case.
