uploading some files with specific file name crashes web interface or causes issues

[bobafetthotmail]

Hello, I recently installed BeePrint 1.6.1 on my FliyngbearGhost 5 with stock firmware 5.91.

I have some gcode files created in the past.

I connect to web interface and uploading files with the File Upload box I pinned to the Home page. I used Firefox, Chromium and Falkon browsers to repeat the test. Also restarted the printer with the power switch.

If I upload files (any file) with the following names the web interface crashes (becomes a gray empty page) and must be refreshed to show interface again. Upload fails.

ramRack05_Desktop_16stick_x2.gcode
ramRack05_Desktop_16stick.gcode
customizable_fan_cover_80.gcode

If I upload a file named "customizable_fan_cover_120.gcode", the file in the SD card is named "customizable_fan_cover_120.gcodeȴ)" in the web interface
so the upload process has appended "ȴ)" to the file name.
If I connect the SDcard to a PC I see that the file name is "customizable_fan_cover_120.gcode却)"
Checking with checksums, the files are the same.

A similar issue (file is uploaded but has symbols appended to the file name) happens also with
hdd_dock_withEnclosure_x2.gcode
