File name is changing

When I attach my file into Attach Image the file name suddenly changes and when I clicked the file link the file cannot be found.


The file name is “UBX-CC_May_1,250_TEE_1 2020-10-30 10_15_02.png”

May be similar same file already exist in the folder.

No, I just attach that file, and suddenly the file name changes on its own.
