Error throws in console when closing a folder in storage

[timea-solid]

Each time I close a folder in storage I get an error like:
manager.js:1767 Uncaught TypeError: Cannot read properties of null (reading 'AJAR_statement')
at q (manager.js:1767:59)
at HTMLTableCellElement.Q (manager.js:2277:7)
I used chrome to check this. See screenshot:

On Firefox the error looks differently in the console.
