What is causing this

For a leather point I think you need a 135x16 LR or TRI  like in this https://www.schmetzneedles.com/item/135X16-DIA-Needle-System-100064

thank for all your help.  looking at what I got i can definitely see the needles are too small.  I found these so I bought 1 of each so I can test out which works better.

This system is also be known as DP X 16. As Brian pointed out, leather point needles in this system are designated as a "16" while fabric point needles are designated with a "17." No change in the needle size, just the point. So a 135 x 16 needle is the same as a DP X 16 needle and a 135 x 17 is the same as DP X 17.

Not sure but I think you might find the 200/25 size needles a bit big for 207/T 210 thread.

I use Organ needles occasionally but prefer Schmetz. I have a PDF copy of the Organ catalogue I found online but can't load it here for you because it exceeds the allowable size. Schmetz and Groz-Beckert both have point style charts online as well. It won't take much digging to find them if you're interested. Sorry I can't give you links but I downloaded them as PDF's and didn't bother bookmarking them.

A number 25 needle pokes a hole suitable for #277 bonded thread on both sides. A #24 needle is best used with #207 thread and a #23 for #138 thread (top and bobbin). If you use an oversize needle the hole will have too much clearance and the thread knots can be hard to position. Knot position should be adjusted by means of the tension sprinbgs for the top and bobbin threads. Knots along the bottom indicate way too much bobbin tension or little to no top tension. This begs the question: is the top thread actually laying well within the top disks and then around the check spring with a click as you pulled it around the disks?
