BPM randomly changes to 145 after 5.7.0 update

yesterday at an event the BPM was acting really irratic.

Deck A would randomly change its BPM to 145.

This happened a couple of times while i was mixing a track into Deck B and wanted to create an 8 bar loop on Deck A to do so. When I hit the auto loop it , the BPM suddenly changed to 145.

Another time trying to mix a track with Deck A , hit Sync and the BPM changed to 145.

I installed 5.7.0 this week and this is the 1st time Ive used the software since the update and 1st time this has ever happened.

I am using a Windows Laptop and Pioneer DDJ SX2

TIA Bart
