A4T reporting issue after Web SDK migration

After Web SDK migration, we are seeing issues in the reports like data is not evenly distributed among the experiences in A/B Test. Although, experiences are getting delivered as expected.

In Adobe Launch, I have a separate rule of Adobe Target which is firing at top of the page (Library loaded) and I am sending a web SDK event as shown below with "Include rendered propositions" checked nothing else in Data, XDM or custom code.

Please help me fix the reporting issue.
