Notification Problems

[kiiiii]

I've been experiencing a problem everytime i copy, delete, or move files in file manager. 

whenever i do the said actions the automatic notification that shows the progress does not close whenever the task is completed and sometimes it remains stuck and i cannot even close the notifications. what can i do to solve this problem?

it usually lags when you modify large amount of files , especially if moving from internal to sd or from within sd card itself. try to wait it out, it would usually sort it self out.

try to modify ( copy pasting moving) small batches of files
