low difficulty share and incorrect extraNonce2 in nonce only with t-rex miner
Hello,

im testing Ergo on main net after on testnet everything went fine. So i connected 10GH/s to my pool. Every rig doing fine but one with t-rex 0.22.1 have 2 type of errors and one with nanominer have 1 type of error.


**Issue 1 with nanominer:**
Share rejected: job not found [nanominer/3.3.5-cuda11] 

**Issue 1 with t-rex:**
Share rejected: low difficulty share (1.622755973752) [t-rex/0.22.1] 

**Issue 2 with t-rex:**
Share rejected: low difficulty share (1.7530226835) [t-rex/0.22.1]

Im using vardiff. 

My config:
  "blockRefreshInterval": 100,
  "jobRebroadcastTimeout": 60,

  "difficulty": 0.5,
  "varDiff": {
      "minDiff": 0.1,
      "maxDiff": null,
      "targetTime": 15,
      "retargetTime": 90,
      "variancePercent": 30,
  }

Thank you
