You can get a similar experience if the middle sear is a fraction too close to the top sear, hard to explain, but obvious when you see it. If this is something that has just started to happen it could be indicative of some damage.

I’d start with flushing out the old grease and re-lubing though.

If you don’t get any further forward with this I’d be happy to have a look at the unit itself, they aren’t particularly difficult triggers to work on.
