OPC UA Client Node - subscription limitation

Hi all,

I am using OPC UA client node to subscribe data points, Is there any limitation in terms number of client nodes. I have used 24 nodes, after that if I add nodes again, shows only subscription id, and payload, some number, but no data. If I disable 2 or 3 nodes, showing data
Before disabling nodes:


After disabling 3 nodes: I am getting payload, working fine


Is there any limitation/maximum for subscription points , like 25 datapoints
