Issue with timestamps creating extra events

[bnichols024]

Certain events in these logs have dates in certain tags below such as <BeginDateTime> and <EndDateTime> . They are creating additional events when they should only be one. Same thing on JMS Timestamp on event 2 pictured below. What would the correct regex be to only make events when the timestamp is first like in 1, 5-9. Thank you.

The props.conf settings are not correct for that sourcetype.  Please share the current settings and also specify where events should begin and end.

I don't have a props.conf file currently configured. That's what I'm asking for help with. I want events to break like they normally would before timestamps, but to not include the time stamps you see in events 2, 3, and 4 in the image. Only timestamps that start a line.
