2 layer PCB with pads on 1 layer for THT components

Hello I made this two layer PCB. For my application the pads of the THT LEDs must only be on the bottom layer of the PCB, which makes desoldering components easier. For that, I just used a finished layout of the LEDs (LEDOrange orange 3AO4UD by LCSC) and modified the pads in the way, that they are just on the bottom layer and then put a hole in the middle of the pad with a diameter of 0.9mm. top layer: ![top.png](//image.easyeda.com/pullimage/KJGRCfF1UNYa9nvgQjoL1NkFWJrhznkchPacKpBK.png) <br> bottom layer: ![bottom.png](//image.easyeda.com/pullimage/KkqS3JxCyipXMTRhkDqxqzTe6KTlBz40AvXnNFSA.png) <br> I got the ordered PCBs today. I discovered that the area for the solder is unexpectedly very small. And there´s a gap between the hole and the solder area with just bare PCB. This confuses me, because at the gerber file there´s no such gab and everything looks fine as I want. As I´m more or less a beginner with Easyeda I´m not sure if it´s a manufacturing issue or an issue by myself. How can I solve this? (The two pads with the red dots are fine :) ) ![Inked20210626_233115_LI.jpg](//image.easyeda.com/pullimage/lysbYvpBXBNzUiLFhLkAE2y0zFqxXWorxcqk9A4N.jpeg) <br> <br> note: My english is not the best, so sorry for any spelling mistakes :)
