Some additional info (might be irrelevant and this might not triggeres this issue happening): after updating to 4.3.1, I’ve synced library from Engine Desktop OS to the SD using the sync function, I did no prior re-analizing of tracks, since it was the same library I’ve used on same device during previous Engine OS version 4.2.0 and just wanted to sync updated grids/cues/etc to the Desktop OS and then back to USBs (I’ve synced from SD card to Desktop Engine OS using the circle sync button next to the drive name in the drive browsing view, which syncs only new changes to tracks to the Desktop Engine OS files)
