HMR to compare multiple header rules

Hi;

Created this HMR which does following;

1. delete route header for INVITE & Register

2. Store Subscribe for ua-profile

3. Store Subscribe for message-summary

4. Delete route header from Subscribe if if matches to 2nd ( checkforeventuaprofile) or 3rd (checkforeventmssgsumry) header rule

The issue I am having is HMR not able to delete the route header if Subscribe has event "message-summary". Can you please provide insight as what's wrong with the logic here and if match-value for 3rd header-rule "striproute" is correct ?
