Tested with:
MC: 1.10.2
Forge: forge-1.10.2-12.18.3.2185-universal
Quark: Quark-r1.1-68 with AutoRegLib-1.0-2

OpenComputers: MC1.10.2-1.6.1.6

Summary:
Not sure who's fault it is but with Quark installed OC's Tables inventory breaks - items cannot be pulled from it if they been put into inventory before quark was installed and items that been put after installation not working correctly.
The original issue thread with detailed info about issue in OC tracker: MightyPirates/OpenComputers#2192

Accessing tablet inventory interface generates some errors in console which i think are relevant to this issue:
