Tag LastChange and Value do not change quickly


I’ve been checking the value from some tags and I see that the lastchange date is not the same what I read with a client OPC (Uaexpert). For example: in ignition’s tag a flowmeter (Kepserver) has 2020-06-01 2:11:13, but when I read with Uaexpert the last value it was at 2020-06-01 9:42:16 and the value is changing because the flowmeter is detecting flow. I’m waiting to update and the LastChange updated to 2020-06-01 2:17:13. The scanclass is Direct 1.000 ms and stale 10.000 ms. Ignition has two OPC: Kepserver (flowmeter) and Ignition OPC server (PLC).

Any suggestion?
